@medellinguru @Tiffany_J fetch_creator_info and fetch_tiers calls failing in your logs. This points to your site connection to api having been broken at one point.
Even if you did it before, apply the steps in the below guide to force refresh your site connection to Patreon.
After that, try clicking refreshing your tiers by clicking the refresh button next to the dropdown in ‘Patreon level’ metabox in WP post editor.
If these issues continue, both of you prepare temporary admin accounts at your site and mail them to ozgur@c.patreon.com - you should not mail any kind of login information to anyone else but this email, and you should delete them after the debugging is complete.
