I upgraded to CiviCRM 4.6.2 on Joomla 3.4.1 last week. Everything seemed to work fine, however, when I tried to send out a New Email today, the CiviMail page did not display, the CiviCRM menu did not properly display nor can it be used to navigate.
I tried to see if the same problem occurs on the Joomla Demo, but CiviCRM is only on Version 4.6.0 there.
The following images reflect what I'm seeing:
All other menu items under mailings display and work properly: Just one example.
However, the new A/B test results in the same type of screen as in image 1:
I've cleaned out the Templates_C directly, along with the site & browser caches, to no avail.
I've got to get this mailing out to our members within the next few days. Any assistance would be appreciated.
