Nick,
As promised, here’s a copy of the message I sent you earlier. Delighted to hear that it worked for you too!
Hi Nick
I actually found a solution late last night, although I don’t know if it’s of any use to you. But basically, I had entered the path to my css file in Tools - Configuration - Interface & Features. That was the only difference I had in my set-up between the live server and the test server, where I had not put this link in and where I didn’t have the same problem with the background image coming through in the editor. The minute I removed the path, things went back to normal for the editor in the live environment.
Please let me know if this helps in your case, then I’ll put it up as a reply in the forum. And thanks for replying to my query anyway even though you didn’t have the answer. That’s what I love about the people on the MODx forum - I am always amazed by how many people on other sites couldn’t be bothered to reply!
