i am using Joomla 2.5.8, and K2 with 2.6.2
And K2 works just fine few days ago but suddenly it just can't add any new items,
when i want to add a new item on back end, and i click new or edit old items, it got blank pages and i can't do anything... but i can edit other tabs like categoray, tags, comments...etc
and i opened the error report after i click new item it shows "Fatal error: Call to a member function getAttribute() on a non-object in /home3/incgsolu/public_html/gem/administrator/components/com_k2/elements/items.php on line 34"
i've googled but still can't find any solutions, is there any help?
i've also attach my Plug-in Manager screenshot and fatal error screenshot.
Thanks,
