OK I backed up my database. I looked over the alertables but the only things I understand are:
require main.inc.php and alter table so I'm hesitant to try anything. Are these alertables necessary? I figured out I ran alertable_demo 5.4.5 (which was the newest alertable) when I first installed the full version. I thought that's what the instructions said to do when upgrading from the trial to full version.

But I'm running into a problem with adding a post and was wondering if these alertables are related to it. When I preview a post I get the following message: (fyi -- paths are abbreviated)

Warning file("http://www.linly.com/ubbthreads/filters/badnames" - Success in /public_html/ubbthreads/addpost.php line 169

Warning Variable passed to each () is not an array or object in addpost.php line 170

But I'm still allowed to post. Following the post I get the above two messages again plus the following:

Warning file("http://www.linly.com/ubbthreads/filters/usertitles" - Success in /public_html/ubbthreads/addpost.php line 767

Warning Variable passed to each () is not an array or object in addpost.php line 768

How can I fix this?

Thanks much
