Something happened on 2023-07-22 and several stations stopped submitting. Why?

Brill! Thanks for confirming that's what was wrong. I must have done something when implementing the control panel. Let's hope it was just a one-off.

I have gone through the submission logs and grabbed the passwords for the relevant stations and put them back into the database. Some but not all also had missing coords, so I simply chose a random spot based on the station location. All of the stations I mentioned previously are now back online with radmon.
