I have a lot errors recently. When opening the main template it gives an erro rendering inner content, I doesn't render a menu "error rendering menu" and Error occurred while saving. The last one ads in de error message "Your server returned a 200 error for the request to undefined". What am I doing wrong over here? Somebody experienced this before. What to do? I am on a bit of a deadline. Is this a bug in Oxygen or is something misconfigured on the serverside?
