I am so sorry if this is a repetition, but I have looked all over and can find no help for this error. I have web services for mobile enabled. I CAN login to the site but if I click on "My Courses" I get the error" Invalid response value detected". This happens on iOS and android so its probably my settings on the server. I might add that Im a first time, very very excited moodle user(administrator? - wannabe at least) so am quite lost at present.
Actually, all other settings work except my courses and Calendar events which both throw up the same error.
