Just downloaded and installed the 2.5SVN over a 2.3 version i installed 'way back', problem is when trying to edit the items in the back end i can't see the content areas under the various tabs.

 

google chrome 'inspect element' suggests that the simpletabscontent isn't displaying the information, but if i drill down enough levels i can see the content (in chrome inspect elements).

 

if i disable 'K2 default CSS' then i can edit items in the backend fine, but the frontend formatting gets lost.

how to resolve ?
