A 403 Forbidden error is an HTTP status code that means access to a specific page or resource is forbidden or blocked. This error commonly occurs when you try to view a specific web page or file and the server refuses to display it or allow access.
Some of the most common causes behind 403 errors include:
- Server or hosting configuration issues – The server settings may not permit access to the requested file or directory. This is often an issue on shared hosting servers.
- File permissions problems – If permissions on files or folders are too restrictive, the server won’t be able to display the page.
- Hotlink protection – Some servers block other sites from linking directly to their images or other files. This anti-theft measure can inadvertently cause 403 errors.
- Outdated .htaccess rules – If the .htaccess file contains restrictions or redirects that are outdated, it can cause 403 errors.
- Plugin conflicts – Security plugins or caching tools may have settings that block access to certain pages, resulting in 403 errors.
So in summary, a 403 Forbidden message means the server has denied access to the webpage or file you tried to view. The error is often caused by incorrect server settings, hotlinking prevention, or restrictive file permissions that block normal access.

Why Does the 403 Error Happen?
There are a few common causes behind 403 forbidden errors:
Server or Host Configuration Issues
One of the most common issues is that the web server or host is misconfigured and is blocking access to certain files or folders on your site. This could happen if directory-level permissions are set too restrictive, blocking the web server’s access. Or there may be rules in the .htaccess file or host firewall that are outdated or faulty, blocking requests.
Checking your hosting control panel for options to update permissions or reviewing server rules can help troubleshoot configuration issues. For managed WordPress sites, contacting support is a good option, since they control the server settings.
File Permission Problems
If file permissions are set incorrectly on your site, where folders/files are blocked even from the server accessing them, a 403 error can occur. This may happen after migrating a site or transferring files.
Running a check/repair on file permissions and ownerships through FTP can identify and fix any overly restricted folders or files causing 403 errors.
Hotlink Protection
Some sites use hotlink protection to prevent unauthorized use of their images and other files. If you have hotlink protection enabled, but haven’t properly allowed or authorized your own domain, you can receive 403 errors.
Temporarily disabling hotlink protection can help determine if it’s the cause. If so, update the allowed domains to exclude your site’s URL.
Outdated .htaccess Rules
For WordPress sites running on Apache servers, outdated or incorrect rules in the .htaccess file can sometimes block access and throw 403 forbidden errors.
Reviewing your .htaccess file for any suspicious or unknown rules compared to the default WordPress version can reveal issues to troubleshoot.
Plugin Conflicts
In some cases, conflicts between plugins with permissions/access rules can lead to unexpected 403 errors. For example, security plugins combined with caching/performance plugins may cause conflicts.
Troubleshooting by disabling plugins one-by-one can identify if a plugin conflict is the cause. If so, remove the problematic plugin or seek an alternative that’s compatible.
Fixing 403 Forbidden error on WordPress
If you get a 403 error on your WordPress site, there are several things you can try to resolve the issue:
Check URL and Domain Mapping
An incorrect URL or domain mapping is one of the most common causes of 403 errors in WordPress. Double check that the Site URL and Home URL are set correctly in your WordPress General settings.
Also verify that your domain is mapping properly to the correct folder on your web hosting server. Many managed WordPress hosts like WordPress.com allow you to map a custom domain in your account settings. Make sure this domain mapping is configured properly.
If the URLs and domain mapping check out, there may be an issue with the .htaccess file needed to rewrite URLs. Ask your hosting provider to verify the WordPress .htaccess file is present and set up correctly.
Clear Your Browser Cache
Before troubleshooting further, try clearing your browser cache and cookies. Then attempt to reload the page that gave you the 403 error. Sometimes your browser caches can hold onto old URL information that is causing the 403 forbidden error, and a quick cache clear will resolve it.
Switch Off VPNs and Proxies
If you are accessing your WordPress site through a VPN or proxy service, try turning off the VPN and accessing the site directly. VPNs and proxies often trigger 403 errors if the IP address you are coming from is blocked by the server configuration.
Update Plugins and Themes
Outdated, abandoned or insecure plugins and themes can sometimes cause 403 errors to pop up without warning.
Log in to your WordPress dashboard and make sure all plugins and themes are updated to the latest version. If the issue started after updating or installing something new, deactivate that plugin or switch to a previous theme to see if that resolves the 403 error.
Restore Your Site From a Backup
If you have a recent full-site backup, restoring your WordPress site from backup can override any problematic files or database issues that are blocking access and throwing 403 errors. Always make sure you have regular WordPress backups in case you need to restore due to errors like this.
Contact Your Hosting Support
If you still see the 403 error after trying the steps above, it’s time to contact your WordPress hosting provider’s technical support team. Give them the specific error details and pages affected, and they should be able to pinpoint what is blocking access to your site and restore things from their backend.
Troubleshooting 403 Errors on Other Platforms
If you encounter a 403 error on a non-WordPress platform, there are a few common troubleshooting steps to take:
Verify Folder Permissions
Check that the folder permissions are set correctly and allow the web server access. The specific permissions required vary by platform, but common recommendations are 755 or 644. Reset any folders throwing 403 errors to the recommended permissions.
Disable Hotlink Protection
Some platforms have hotlink protection features that block other sites from directly linking to your assets. This can accidentally block normal user access too. Temporarily disable hotlink protection and test if the 403 error goes away.
Clear Application Cache
The application itself may be caching incorrect permissions or rules that are causing the 403 error. Clear any cached config files, policy files, or application data files to force a refresh.
Check IP Address Access Rules
Firewalls, security apps, IP restriction rules may be blocking your current IP address. Add your public IP to the allowlist if possible. Try accessing the site from a different network location as well.
When to Contact Your Host/Admin
If you’ve tried the basic troubleshooting tips outlined above and are still seeing the 403 forbidden error, it’s time to reach out to your web host or site admin for further assistance. Here are some instances when contacting your host is the next best step:
- If basic troubleshooting doesn’t fix the issue – After trying steps like clearing your cache, updating plugins, and double checking file permissions, the 403 error persists. This likely indicates there’s a deeper issue that requires investigation by your host.
- For major site restores or migration assistance – If the 403 error started after migrating your site or restoring a backup, there may be configuration conflicts. Reach out to your host to help properly map the domain and undo any problems from the transfer.
Your hosting provider has more advanced tools to debug what’s causing the 403 forbidden error behind the scenes. They can check server logs, analyze connectivity issues, restore previous versions of your site, and edit the backend configuration. Don’t spend too long troubleshooting on your own before seeking assistance. Most quality web hosts have 24/7 customer support and can resolve these types of errors quickly if you provide detailed information.
Preventing 403 Forbidden error in the Future
Keeping your site updated and regularly backing up files can help prevent many 403 errors from happening in the first place. Here are some key prevention tips:
Keep plugins and themes updated – Outdated plugins and themes are a common source of 403 errors. Regularly check the WordPress dashboard for any available updates, and apply them right away. This ensures any bugs or conflicts causing 403 errors are resolved in newer versions.
Monitor server logs for issues – Many hosts provide access to server logs, which can show you any 403 errors happening behind the scenes. Review these periodically to catch small 403 problems before they escalate.
Use firewalls and IP blocking carefully – Overly restrictive firewall rules and IP blocking settings may inadvertently block some legitimate access to your site, triggering 403 errors. Only use these security tools if you fully understand how to configure them correctly.
Frequently backup site files – Having recent backups of your WordPress installation and key folders like wp-content can make restoring your site very quick if a major issue causes widespread 403 errors. Back up daily or weekly to enable easy rollback.
Conclusion
403 Forbidden error can seem intimidating at first but they are generally fixable with a few troubleshooting steps in most cases. The main causes of 403 errors are related to configuration problems, plugin conflicts or broken .htaccess rules.
With WordPress sites specifically, checking site URLs/file permissions, clearing caches and updating plugins/themes usually resolve many issues. For other platforms, validating folder permissions and IP access rules can quickly fix 403 problems in the right circumstances.
While complicated cases may require contacting hosts, the majority of 403 Forbidden error only demand minor tweaks and troubleshooting. Prevention is also straightforward – keeping software updated, managing plugins, checking permissions/access rules and maintaining clean site files will help avoid 403 errors in the future.
403 errors may temporarily block access but they indicate fixable configuration issues more than major corruption or threats. With a few targeted steps, most 403 errors can be eliminated so users can quickly regain access to sites and content.
