When I updated this morning, I got the error 'Unexpected token <' numerous times. Also, many other plugins didn't load, or loaded incorrectly/wonky including Post Grid. When Post Grid is deactivated, all plugins work correctly and the errors are not present. Please help!
Welcome to our forum.
I just logged in your admin, can see post grid is deactivated, can i activate it to regenerate the errors?
