Please allow me some time. I am checking your issue.

hello, I have reinstalled the Template Gazette on a new subdomain (current quickstart package). Then I installed all updates except for Helix Ultimat 2.03. adding feature images still works. However, when I install the update for Helix Ultimate 2.03, adding feature images no longer works. so it seems to be due to this update in combination with the template gazette. hope it will help you solve the problem. best regards

Yes, it is the issue. Please wait until we update the templates. It will be updated in this month, hopefully.
