406 Not Acceptable error when posting an image

[louage]

Afternoon all,

I recently had some kind of script injection problem on my board - a line of code was added to my forum templates causing a dodgy pop up to appear. It also managed to somehow email all of the members using the forums internal emailer (using an email address I only used on vBulletin )

A randomly numbered php file (e.g. 31433.php) appeared in every single folder on the server (vbulletin or not). I removed all of these, and also found that a dodgy entry had been inserted into all the .htaccess files, so I have removed all of these (not sure if that caused this problem?) and re-created a blank one with the following inside it:

Options -MultiViews
ErrorDocument 404

I've only inserted this into the /forum and /forum/includes folders.

Anyway, since I've done all this users seemingly cannot post images using [ img ] http://whatever.com/a.jpg [ /img ]. It comes up with the following error:
Not Acceptable

An appropriate representation of the requested resource /forum/newreply.php could not be found on this server.


I hope I've posted enough detail for someone to have an idea. Any thoughts on this would be very much appreciated

Louis.
