hello,

When I am trying to select or change k2 article category in the backend I am getting error:
1. I am opening editor by 'create article' in k2 backend,
2. when I am trying to choose category the selected category appears for a while on a page, but after few seconds is reloaded to the other blank page which is still loading without effect.

What is the problem? I have changed server in last days, I havent similar problems yet.

hope to hear you

thankyou
