Hi Pavit
Sorry for the delay in response - had a few deadlines...
I have added Superuser Logins in the form provided.
NOTE: This is a copy /sub-domain of an existing site on the same server and I am having some problems with redirects, so please pay attention to the url (must be 2019.tul....)
Besides megamenu not loading, the layout preview and positions also does not load under templates/styles/layout. I used to be able to disable modules and change widths with a click and drag?
Then also the two module positions: "position-3" and "position-4" did not allow me to publish in then. I added these to the templateDetails.xml file and fixed my problem - Just thought I will let you know.
Thanks in advance for looking into this problem.
Warmest regards
