Hi guys!
I'm running my site on my local server at this time. After installing k2 all my content disappeared. When I mouse over the place it should be at and click the mouse and pull it, I can see the content is there but actually all the pages are blank.
After deleting k2 all content appears again. I tried k2 v 2.6.1 and 2.5.4. Same result.
Can anybody be of any help?
Thnx in advance!

Be carefull about uninstaling k2 if you have k2 content, as you will loose it.
Try going to the k2 dashboard - paramaters - and setting the javascript loading at the top of the layout tab to "local copy"
