On a side note, it would be nice if the diagnostic report omitted the PERCH_MAILER_PASSWORD variable, like it does the DB_PASSWORD one. Just something I've noticed. Cheers.

Hi Drew. Adding that extra constant doesn't appear to make a difference.

Yes, it occurs when saving any region on any page. I've also noticed that an error occurs during login too:

PHP Fatal error:  Call to undefined method PerchAdmin::event() in /admin/core/lib/PerchAuthenticatedUser.class.php on line 96

PHP Fatal error:  Call to undefined method PerchAdmin::event() in /admin/core/apps/content/PerchContent_Region.class.php on line 381

Basically, the login stops on a blank page (because I have display_errors turned off). I then have to refresh the blank page again to actually get logged in.

Hi Drew. I think I've fixed the issue. I compared all the files in version control and somehow it looks like when we overwrote the old core folder with the new one the PerchAdmin class file never got copied. Now I've updated that file everything appears to work nicely.

Thanks for your help.
