I need help

Hi,

if you cant wait on an Solution: i would delete per FTP the Homepage and restore your Backup. So you have your 3.3.6-Joomla and a working Homepage. Maybe you get in the Meantime Help.

Regards

thanks, that's what I did, i restore the backup I took before..

Have you an idea when K2 will be upgraded to fit joomla 3.4?

Which version of K2 where you using?
Also which other K2 related plugins where you using?

I used K2 2.6.9
and plugin
System - K2MultiImages
DJ-MediaTools Source - K2

Try deactivating these two extensions.
Furthermore I noticed other extensions that have issues with J! 3.4 (unrelated to K2).

I would suggest updating all of your extensions and if the issue persists roll back to 3.3.6 until all extensions are ready for Joomla! 3.4
