Hello,

Which version of Joomla! and K2 are you using?

Hello Krikor,

Thanks for answering the Joomla version is 3.4 and K2 is 2.6

You should update to Joomla!'s and K2's latest versions (you should backup first).

As for the error, these are notices and they will not affect your site's functionality.
In the whitepage is there a Fatal Error being recorded?
