I searched for a similar problem but I couldn't find anything so... Anyway, I first noticed it in my Art Freebies topic/thread and it says: "Warning: Missing argument 2 for cache_set(), called in /www/subeta.net/include/mvc/models/forums.php on line 653 and defined in /www/subeta.net/include/cache.php on line 16"

It always appears at the very top of the page. I thought it was just my topic but then I realized that it happens on every topic that I open in the forums. This never happened before. Other parts of the site is fine. It's just the forum topics.

Is there something I'm doing that causes it from appearing? I'm using Mozilla and I haven't tested it on Chrome because for some reason Chrome keeps crashing on me so I've uninstalled it long ago.

I'm getting this as well. Also using firefox.

Same here.

Yup, same here, Chrome.
