How to Fix Litespeed Web Server Error: “406 Not Acceptable This request is not acceptable” on WordPress


LiteSpeed Web Server is the leading high-performance, high-scalability web server.

I found this error when I tried to save post (press Update button) in WordPress.

To fix this problem, modify .htaccess file inside the website folder and put in these lines:

<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
