Php-Notice in index.

[Satyr]

I have the following message in the gallery index if debug-mode is enabled:

Notice: Undefined index: cat_thumb in /www/htdocs/gothic/gothicmodels/gallery/themes/gothicmodels/theme.php on line 1046

I have this code there:
                '{CAT_THUMB}' => $category['cat_thumb'],

What can i do?

Turn off display of notices in debug mode, it is not a significant error.

in fact you should only enable debug mode if you actually experience any issues and you know what the error messages actually mean. PHP has three error levels: errors, warnings and notices. Notices usually are only meant for coders to trouble-shoot. You should always leave them off, as the notices probably don't mean anything to you anyway.
