Thanks Lely - I am checking with my hosting co to get them to increase the memory. Doing it myself isn’t working.
Before I get into this I want to say thanks everyone for taking time to help!
So I can get Cornerstone to load from the Dashboard > X > Cornerstone. And from there I can edit pages. But if I try to create a new page or post, I click the Cornerstone Tab, and then the button “Edit with Cornerstone”, but Cornerstone doesn’t load. After the screen refreshes, I am in the Text editor.
Hopefully increasing memory limits will fix this?
