Hello, I'm transferring site of a Reseller Hosting to another and I am with this link in error_log:
[22-Jun-2016 18:13:09 Etc / GMT] PHP Fatal error: Class 'K2HelperUtilities' not found in /home/*****/public_html/administrator/components/com_k2/helpers/html.php online 56

All permissions are correct, clean temporary files, PHP and MySql correct and was transferred by Akeeba. Panel on Administration K2 is with blank page, the Home also is blank.
In another VPS server also occurred this problem.

Hello,

Which version of K2 and Joomla! are you using?
Is this a fresh install or it started doing this out of the blue?

Did you install any other K2 related extensions?
