How to Fix a 406 Error Not Acceptable “Error” on a Website

The 406 error is a status code returned by a server when it can’t send data to a client in the format it requests. Most web browsers will accept a file that contains the file extension */* in the Accept header. This is how clients signal what type of content to send and define priority lists. */* usually has the lowest priority. Despite its low priority, this file extension is widely used. Fortunately, there are a few things you can do to fix it.


A 406 error on a website is usually caused by poorly coded forum software. It’s also possible that a mod_security rule is blocking requests for your site. Disabling one rule is preferable to disabling them all because that keeps the bulk of your shield functioning. Disabling them all will leave you with no shield at all. The following are some simple solutions to fix a mod_security 406 error on a website.

If the error is happening on a media platform, try logging in to another machine. You may be able to replicate the problem on a different computer, but it’s not always possible. To do this, make sure the two machines are on the same network. Otherwise, the problem could be in the network. Search for support documentation and forums for the platform that caused the error. You can even try removing the plugin to see if that fixes the problem.
