How to Fix the 405 Method Not Allowed Error
1. Backup Your Site First
Always take a backup of a WordPress site, including its database, before making any changes; so that if anything goes wrong in between the troubleshooting, valuable information is not lost in the process.
2. Check Your .htaccess File
The .htaccess file contains many server rules that can allow or forbid request methods.
- Using FTP or File Manager, access the files of your WordPress site.
- Locate the .htaccess file in the root folder.
- Temporarily disable the file by renaming it as .htaccess_backup.
- Check the website for the presence of a 405 error.
- Should the error vanish, then you should regenerate the .htaccess file by going to WordPress Admin > Settings > Permalinks and hitting the “Save Changes” button.
- If the problem does return, then you might want to review your server configuration or plugins.
3. Disable All Plugins and Themes Temporarily
The 405 method not allowed error often arises due to plugin or theme conflicts.
- Deactivate all plugins using the dashboard or rename the plugins folder via FTP.
- Switch to the default WordPress theme Twenty Twenty-Three.
- See whether the error 405 pops up or disappears.
- If it disappears, start activating plugins one by one testing each until locating the possible culprit.
4. Check Server and Hosting Settings
There are times that the hosting provider may restrict certain HTTP methods for security reasons.
• Reach out to your hosting support and ask if they are blocking HTTP methods.
• Ask for any blocking methods needed, like POST or PUT.
5. Inspect Web Application Firewall (WAF) Rules
Some security plugins or firewalls can block different request methods, which gives a 405 not allowed error.
- Turn off security plugins or WAF temporarily
- Check to see if the error gets resolved
- You could also adjust the settings of the firewall to allow the required HTTP methods
