Mailings - Disabled Next/Test Buttons
Unfortunately, my last post affirming that the problem is real and still present in the current version was deleted because the moderator thought it would be better as a 'comment' without realizing that commenting is disabled for most users. I'm not yet certain of the cause but there are a few fields in the civicrm_mailing table. In particular, the reply_id field (and a few other suspects) look like they may not be getting updated properly.
Nicholai, I'd have been happy to post this as a comment if you would be kind enough to enable commenting for individual's with a reputation of less than 50.
