Two errors after installing

I have two fairly big errors after I've installed (downloaded today)...and I searched the other thread but couldn't find either.

1. Every single post is duplicated. No matter what. If you make a post, you get the "this is a duplicate of one in the last XX seconds" message and get redirected to the thread...where you can see your post.

2. When I start a new thread and/or run the Mass Forum Settings, I get an error... Invalid Argument in foreach() in vbplaza_forumdata_start.php, line 21.

??????

Ok...I think I have a product conflict...I turned off another product, and that did it...

Any ideas where I should start troubleshooting that other code? Which hook would be the most likely to call these sectons? (they share about 6 hooks)

I had this same error, rebuilding bitfields fixed the error messages however the changes I apply in mass forum settings do not get applied. (it says they get applied, but then the old values are there)

also I don't have that private threads hack installed.

*edit*
ok, apparently the settings get applied when I view the forum settings, it just keeps the old values in the mass forum settings area.

The mass forum setting numbers will always be the default in that version. In v1.5.1, they will be blank. The settings really do get set to the forums, but they are not a global setting anywhere, it actually sets the setting for each forum and not some global setting somewhere.
