How to make close save bar work after joomla 3 update?

Question

CMS

Put the template quickstart option with demo data.
Then I updated Joomla. 3.2 to 3.3
Then I updated j2store, at first I thought that the problem was with it, but the problem is the same for all modules.

the panel selected in a rectangle does not work.
And in all modules.
Looking forward to your valuable advice.

Answer 1

"Running" of all new modules for CMS should be done only on a clean TEST system with the same CMS.
Versioning of working and tested configurations should be maintained.
It is possible that there is a conflict between modules.
