How to Fix Error 501 Not Implemented

5xx HTTP status codes indicate that there’s an issue on the server side. However, there are cases in which 501 Error appears in the case of a client-side issue. In the following paragraphs, you will read about 7 methods that fix issues appearing on both the client- and server side.

 

Method 1: Reload the Web Page

Reloading the requested page is the easiest method to fix 501 Error. The issue might appear because of some momentary miscommunication with the server or a more general Internet problem that results in the display of an error message.

This is why, when you see Error 501 displayed, the first thing you should try is to reload the page and see whether the requested resource is delivered properly.
If the problem is not fixed after a reload, continue with the next method.

 

Method 2: Clear Browser Cache

Every time your web browser loads a new web page, certain files are stored on your device. These files are called cache and help the web page load faster the following times you open it, so the overall web browsing experience becomes smoother.

However, too many cache files can clutter your web browser and negatively impact performance. This is why, these files should be periodically deleted, so they don’t cause any technical issues.
Delete your web browser cache and try to reload the page. If you don’t know how to do so, read this article:

However, if deleting the cache doesn’t help, proceed with the next method.

 

Method 3: Scan Your System for Viruses

Sometimes, viruses and malware might be the cause for seeing 501 Error. This is why, you should perform a virus scan. Should issues on your system be found, fix them and check if you can access the requested page again.
If the error message 501 Not Implemented is still present after the neutralization of viruses and malware, then proceed with the next method.
