Hey Guys,
For the benefit of the community - if you have installed K2 and are having blank page issues, by this i mean via admin panel you try to add or trash an item or category and in the process it runs and returns ZERO errors and displays a BLANK (WHITE) page. Then do the following and see if it corrects it.
Disable the plugin "Smart Search - K2" under manage admin section.
I've tried to resolve this issue for 2 weeks, googled, search K2, there is very little info on how to resolve this but a lot of complaint.
So hopefully this works for others.
Cheers
