VERY BAD ERROR!!!

[Nitro]

I hope someone can help me, i went to change the forum settings under the location for server settings then i get the following error:
Notice: Undefined index: theme_template_error in /homepages/42/d87747679/htdocs/melabb/Sources/Load.php on line 816
i have uploaded another back up copy of the total forum files, but my guess is,
if i installed again the forum is it going to fix it? or
do i have to access MySQL and change and undo what i did?

please help soon.


thank you
