hmmmmm... so that error:
Fatal error: Class 'Subscribe2_List_Table' not found in /mnt/target06/346262/394688/www.aspenreallife.com/web/content/wp-content/plugins/subscribe2/admin/subscribers.php on line 136
should only be appearing basically if there is an incomplete installation of the new files?
so weird as if you let the page sit for like a minute, then refresh the content appears fine.. but the client isn't going to settle for that. Could it possibly be some sort of timeout issue?
Edit: just noticed 8.7 was released... might try upgrading to that to see if it helps!
Post edit: SUCCESS! Things are working great now! Thanks so much for your devotion to address my issues. Out of curiosity, what changed since the dev version?
