Well line 429 of that file is this
Code:
Content visible to verified customers only.
I really do not see why you should get an error with that line it has been in existence for awhile. Maybe a change in vbulletin?
Did you do anything like upgrade your forum. From what I see in vbulletin they call things like this
Code:
Content visible to verified customers only.
Maybe try upgrading your gallery files. I was thinking this is maybe a PHP issue but the line your only 2 errors point to something with the bbcode parser. I will have to check into 3.87
vb and see if they changed anything but other than this one issue I see in the gallery I really can not comment on the forum errors in your post.
You can turn off your gallery and use your forum sure.
