Hi, I've not touched my htaccess file, but all of a sudden, I'm getting a 500 error on all my pages except /forums/ Can this happen without htacess modification?
The 500 internal server error is a very general status code that indicates an issue on the server side. There are many potential reasons for this to happen and .htaccess is only one of them.. But if you recently made changes to .htaccess, this is a good starting point to look for errors. Check your apache error log for more detail.
If there're recently mod_sec installed, be sure to check that you don't have 777 CHMOD files. Also, contact your web host for further information...
