My b2evolution Version: 1.10.x

Hi there,
I just tried to upgrade from 2.4.0 to 2.4.2 and got a little problem going.

I get the following error message:

Notice: Undefined variable: credit_links in /home/nicolebo/public_html/b2/inc/_vars.inc.php on line 184

Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /home/nicolebo/public_html/b2/inc/_vars.inc.php on line 184

Fatal error: require_once() [function.require]: Failed opening required '/home/nicolebo/public_html/b2/inc/items/model/_itemlight.class.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/nicolebo/public_html/b2/inc/_core/_class4.funcs.php on line 40

I tried to delete that _vars file mentioned.
Well, my error message got shorter but it is still there.

I used the zip files for the upgrade and must have messed up somewhere along the road....

Grateful for any help!

Nicole :)
