Looks like your attachments URL is wrong.
Ok, I need to clarify something. If you use two URLs for your site, this mod is NOT for you. YaBB SE fixes this problem by using full URLs - thus, you get redirected to the correct working one. This mod uses short URLs.... so it *doesn't* switch the URL.
For example... if I go to your site and log in via:
http://www.200mph.org.uk/index.php?action=loginAnd then go to this URL:
http://www.200mph.net/yabbse/index.php?board=1I will NO LONGER be logged in. This is something MSIE does... nothing I can prevent. Thus, they will appear not to be logged in.
I recommend you either do not use my mod or you pick one of the URLs and use a simple redirection script for the other...
(Save this as index.php...)
<?php
header('Location: http://www.200mph.net/yabbse/index.php' . (empty($QUERY_STRING ? '' : '?' . $QUERY_STRING)));
?>
This will fix the issue - you will only be able to access the forum from the .net address, where it *seems* to actually be hosted.
Lastly, set your attachments URL to:
http://www.200mph.net/yabbse/attachmentsAnd that will fix the attachments problem.
