There seems to be a problem with Nabble forums where Google Analytics is only able to be embedded when the id ends with a single digit, after the hyphen. I found this out when I got over ten Analytics profiles(multiple website, btw), and Nabble began rejecting them.
So, as of now, Nabble allows this false id to be entered: UA-XXXXXXXX-9
But it rejects the true one: UA-XXXXXXXX-18, and shows the message "Enter a valid analytics account ID."
Just to make sure it was the extra digits, I did the following tests:
UA-XXXXXXXX-5: accepted
UA-XXXXXXXX-9: accepted
UA-XXXXXXXX-10: rejected
UA-XXXXXXXX-11: rejected
UA-XXXXXXXX-12: rejected
UA-XXXXXXXX-18: rejected
UA-XXXXXXXX-222: rejected
Is this an error or is it meant to work this way(as a limit for too many tracked forums)?
