XF 1.4 sudden could not be found error - Use Full Friendly URLs - forum url only

[Jordyn]

hi,

as of today, im not sure why this has suddenly happened. but when i try to access a forum URL i get an error saying "The requested page could not be found". this seems only to be effecting forum url's only as of like 30 minutes ago. this does not seem o effect thread urls, i can access threads but not forums.

ive had "Use Full Friendly URLs" enabled for over a week with no issues, but as of 30 mins ago, accessing forum urls example: http://www.forum.com/baily-tent.5/ gives a "could not be found error".

but when i disable "Use Full Friendly URLs" all comes good. again this has just suddenly happened with nothing new installed.

client forum is istalled in root. this is .htaccess code:

#    Mod_security can interfere with uploading of content such as attachments. If you
#    cannot attach files, remove the "#" from the lines below.
#<IfModule mod_security.c>
#    SecFilterEngine Off
#    SecFilterScanPOST Off
#</IfModule>

ErrorDocument 401 default
ErrorDocument 403 default
ErrorDocument 404 default
ErrorDocument 500 default

<IfModule mod_rewrite.c>
    RewriteEngine On
    # Redirect non-www to www
    RewriteCond %{HTTP_HOST} ^forum\.com [NC]
    RewriteRule (.*) http://www.forum.com/$1 [NC,QSA,L,R=301]

    #    If you are having problems with the rewrite rules, remove the "#" from the
    #    line that begins "RewriteBase" below. You will also have to change the path
    #    of the rewrite to reflect the path to your XenForo installation.
    #RewriteBase /xenforo

    #    This line may be needed to enable WebDAV editing with PHP as a CGI.
    #RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

    RewriteCond %{REQUEST_FILENAME} -f [OR]
    RewriteCond %{REQUEST_FILENAME} -l [OR]
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^.*$ - [NC,L]
    RewriteRule ^(data/|js/|styles/|install/|favicon\.ico|crossdomain\.xml|robots\.txt) - [NC,L]
    RewriteRule ^.*$ index.php [NC,L]
</IfModule>

fyi: Index Page Route: is set at forums/
hoping for a quick fix please?

edit: added $config['enableListeners'] = false; to config, still errors.

If you haven't made any changes yourself, as the problem has suddenly started, you should contact your host and ask them what has changed on the server.

i was thinking along those lines, but, all i did was change styles to default, then change back to forum style and the error was gone.

thanks Brogan, if it does happen again, i maybe blaming a template edit, as im basically my host of my server and i didnt change a thing.
the only templates that were edited over a few days ago was adding:

<script src="/mediaelement/build/jquery.js"></script>
<script src="/mediaelement/build/mediaelement-and-player.min.js"></script>
<link rel="stylesheet" href="/mediaelement/build/mediaelementplayer.css" />
<script>

to "PAGE_CONTAINER" template.

and editing attached_files with a media code. which worked fine.

would you think this would effect rewrite .htaccess?

cheers and thanks for your support.
