Using the cornerstone page builder and trying to use a Themeco Header, it shows an error. In Cornerstone itself and it you create a page and try to insert a pre-built template. Different domains with all permissions correct.
Ex. Create New Page > try to insert “Save the Date” > Error: “Uh Oh, Failed to save template”
Ex. Create Header Using Sidebar menu in Cornerstone > Choose Themeco > Choose “Almost Any Page
At All” > Error: some weird compression thing with a code for each one.
Is this a known issue?
