Got to be the most inane ? of all, but I can’t install a downloaded template file (Optimas, and also Brenda-Construction) from ThemeForest site) to my Joomla 3.9x site. Installer requires a Package file (.zip) but of course the files didn’t have one.
In desperation I tried to zip file the entire folder contents, and separately just the Assets folder and neither one worked. Error: no XML file found…
Tried also from Folder location. Same failure.
I’m in hour #6 on this and gotta get some help. Thanks to whoever can!
