First : I get an error every time, when i submit an article from backend
Cannot redeclare class Services_JSON in
public_html/administrator/components/com_k2/lib/JSON.php on line 128
I got same error on site page also on administrator page, then as advised by some member here, i tried it
In /public_html/components/com_k2/models/item.php change the line
if (!class_exists('Services_JSON')) require_once(JPATH_COMPONENT_ADMINISTRATOR.DS.'lib'.DS.'JSON.php');
Solved the problem for me, it seems something else is also using JSON.php.
But Problem is same, seems to b solved on front end, but same here onadmin panel.
No 2 : There is No image styling in home page/ Category View pages, all images are overlapped, and posts too
Just my 2 cents
