Hi all,
Just to share a problem I encountered and how to fix it.
I had an Error 0 when I went to a K2 category page. This was only happening to one category, when I changed category in the menu, everything went ok. I disabled SEF, still got the Error 0 page. SO I checked all my category setting, but to no avail.
It turns out that a member of the website team had made a new K2 element in that category and had wrongly placed text info in a date extrafield. This made the element corrupt and in the process, category couldn't display either. So.... if you get an Error O page on a K2 Category display, check out the elements that are in that category (ie: unpublish all elements & try, then republish the oldest elements and suspect the newer onesà
I spend half a day trying to figure out what was haywire. Hope this helps.
Cheers
