Cheatin' uh? When creating newsletter (as super admin)

Hey,

when i trye to create a new newsletter it gets instandly safed as a draft (ajax loading on the button, and after that ive get redirected to a site saying "Cheatin’ uh?"

any ideas on this? i had activated the plugin before the error with the user edit (there wasnt a similar problem) and now that this is fixed i have again activated it and it came up with this new problem.

one more question on the site, how do i sent an email to all site admins in my network?

with kind regards
patrick
