I am using both X and PRO on different sites on different servers and different hosting companies and all of a sudden I can no longer save changes or create new Grids in Essentials Grid in either theme.
X - 5.2.5
Essentials Grid - 2.1.6.2.1
PRO - 1.2.7
Essential Grid - 2.1.6.2.1
Has anyone else come across this problem? There also seems to be something weird going on with the interface in the X installation, see the screenshot:
