I have upgraded a site to DNN 7.2.1 following the recommended path from 5.6.8
If I stay in the skin MinimalExtropy, all seems fine.
If I change even to the Gravity skin, much goes wrong:
using "settings" on a page shows the settings dialog, but no changes are made on "update"
it is impossible to change out of the new skin without renaming the skin folders on the site, forcing a return to MinimalExtropy.
It appears that some part of the support for skins has disappeared.
Any suggestions of how to rescue the site?
Thanks JC
