datatype error in a php file

[imprezion]

just got my database connected, imported, and running on a new server...but there is an error on the top main page of my forum saying...


Warning: in_array() [function.in-array]: Wrong datatype for second argument in [path]/includes/functions_forumlist.php(395) : eval()'d code on line 6

Warning: in_array() [function.in-array]: Wrong datatype for second argument in [path]/includes/functions_forumlist.php(395) : eval()'d code on line 1

it only shows on top of the main forum, not sub forums or threads/posts.
may be something wrong about the database import? or some other issue in "Styles and Templates"?
anyone know about these two warnings and problems?
should I try upgrading it to Vb4.0 from 3.8.4 now and see if this can be resolved?

thanks
