I've had another look and the *may* be missing parenthesis in a plugin - I say may as I think it should be OK anyway, but if you could edit the Add Useragent String to New Posts and Add Useragent String to New Threads plugins and change

if ((($vbulletin->options['ua37_enabled']) && ($_POST[preview] != "Preview Post")  && (!in_array($styleid,explode(",",$vbulletin->options['ua37_not_this_style'])))) && (in_array($threadinfo[forumid],explode(",",$vbulletin->options['ua37_this_forum_only'])) || (trim($vbulletin->options['ua37_this_forum_only'])=="")))

to

if ((($vbulletin->options['ua37_enabled']) && ($_POST[preview] != "Preview Post")  && (!in_array($styleid,explode(",",$vbulletin->options['ua37_not_this_style'])))) && ((in_array($threadinfo[forumid],explode(",",$vbulletin->options['ua37_this_forum_only']))) || (trim($vbulletin->options['ua37_this_forum_only'])=="")))

and see if that fixes things?

-----

For a reality check - the logic for adding the useragent string is as follow:

IF the product is enabled, AND we are not previewing the post AND the user is not using an excluded style are all true

AND

We are in an forum where UA strings should be appended OR no forums are specified (ie. append in all forums) are true

THEN add the UA string

this sound right?
