XF 1.4 Watch forums: The server responded with an error


Well-known member
Attempting to click "watch forum" on my boards is resulting with an error:

The following error occurred
The server responded with an error. The error message is in the JavaScript console.
Console details, hopefully useful?

As it's a link for registered users, I can't see the exact link to determine what's going on, but it certainly looks like a certain type of error has been thrown and you've been redirected by Apache. This is probably something like mod_security. In your .htaccess, you can add:

ErrorDocument 401 default
ErrorDocument 403 default
ErrorDocument 404 default
ErrorDocument 405 default
ErrorDocument 406 default
ErrorDocument 500 default
ErrorDocument 501 default
ErrorDocument 503 default
And that may show the real error. Any log would actually be in your web server error log.
