[bug fix] Sendy Self Hosting Mailing Software Errors

Sendy.co mailing software. Self-hosted.

Something broke recently, causing a few critical 404 errors and mailing to selected lists not executing. New campaigns get added successfully to lists, but upon sending getting 0/0 sent. All lists worked previously, app worked previously, no apparent changes were made.

Already followed troubleshooting FAQ, issue unresolved.

Please quote fee for troubleshooting / fixing.

Ideally would like to find somebody good at this stuff, we always need help with all kinds of software / apps.
