I'm having the same problem again. It was working fine on Sunday when I was working on the website and the pages that I have added the CMS to are working fine, but I'm trying to add more pages and I keep getting the "Content Not Found" error. Sometime the connection test fine and I will sometimes run a test of adding just one word to the CMS and it will usually do it, but when I try and do the actual content it will not work. When I test the connection, I will sometimes get this error. Not every time, just sometimes.
