How to Fix 405 Error Method Not Allowed
There are five methods that you can apply to fix the problem:
Method 1: Check the URL for Errors
HTTP Error 405 can be prompted by a mistyped URL address. If the requested URL address contains any illegal symbols, typos, and white space, the server is likely to display various HTTP status codes such as 405 Error. Check carefully the requested URL and fix any errors you notice before requesting the online resource.
Method 2: Revert Recent Website Updates
In some cases, 405 Error can be prompted by website updates. If you have noticed that HTTP Error 405 appears after recent updates, then revert to an older website version prior to the changes.
Method 3: Check Website Extensions/Add-Ons/Plugins
If you use a CMS such as WordPress to craft your website, the issue might be rooted in the recently installed extensions/add-ons/plugins.
To see whether the problem lies within the extensions/add-ons/plugins deactivate them. Once you do so, check if 405 Error is still present on your website – if not, then the problem is rooted in one of the deactivated extensions/add-ons/plugins. Should this be the case, then follow these steps to resolve the issue:
- Activate one extension/add-on/plugin and keep the rest deactivated.
- Try to load the requested web page.
- If it loads properly and doesn’t display a 405 Error, activate one more extension/add-on/plugin and try opening the page again.
- Activate extensions/add-ons/plugins until you stumble on one that prompts HTTP Error 405.
- Delete this extension/add-on/plugin or contact developers for further assistance.
Method 3: Check for Database Changes
Check your website database for modified items and unwanted changes.
If you notice such, revert to the original options, or revert the version of your website to an older one.
If you are using a CMS for crafting your website, keep in mind that some of the installed extensions/add-ons/plugins might interfere with the website’s database.
For example, numerous WordPress plugins can access the site’s database files and can interfere in various ways.
Should this be the case, then deactivate all your installed extensions/add-ons/plugins and see whether the 405 Error is still present. If not, then the problem lies within some of the extensions/add-ons/plugins – activate them one by one and open the website to check whether the error message appears. Once you activate an extension that prompts the HTTP Error 405, delete it or contact developers for further assistance.
Method 4: Check the Website’s Code and Scripts
If you have noticed that the error message started to appear after recent code changes, then the problem might derive from some errors within the code itself. Carefully check the code snippets on your website and search for errors, typos, and whether the correct coding language is used.
Method 5: Fully Restore the Website from a Backup
In some rare cases, 405 Error might appear due to compatibility problems with the server. If nothing else helps to solve the problem, then restore a previous version of your website from a backup.
