Can't save Page specific tracking settings

When I try to change page specific tracking settings, the settings don't save. They are stuck on the default of "Add if the following PHP code returns TRUE (PHP-mode, experts only)." and the php code is set as " return false; ". So, I have no tracking.

I think this is related to having upgraded from 5.x to 6.x. I looked for return false; in the variables table, found it (the old analytics module appears to have use "pages" for the variable name), and deleted it. I uninstalled then reinstalled GA. I upgraded from GA 2.0 to 2.2. None of this has worked. I can't figure out where it is getting return false; !

Can someone please suggest where to look, or another method to try?

Thanks, Lily
