Hello,
I've updated K2 component from 2.4 to 2.5.1 in my J!1.5.23 site but now:
- the "categories" item menu voices don't work. There is only a blank page (cart3.altervista.org/index.php?option=com_k2&view=itemlist&layout=category&task=category&id=1&Itemid=53 for example). The other type of menu items seem to work (cart3.altervista.org/index.php?option=com_k2&view=item&layout=item&id=1&Itemid=98);
- in K2 backend no text editor works in Item edit pages (but work for example in Categories Edit Pages). I'm using JCE 2.0.15, but I tried also with Tiny or the default one.

I tried also to reinsatll the 2.4 version of K2, but I don't find it on the web.
Can anyone help me?
Thanks!!!!

Solved. There was a "bad" component: K2 Multicategories.
I've... mono-categorized all articles, uninstalled the component and
reinstalled K2 2.5.1. And now it works.
Thankyou.
