meanwhile I've done a few checks myself.
No storage space issue with the database.
I can add a record manually to the main table - to the extra sensor table
still to be verified it works equally well.
All looks like an application error ...
what is strange that both databases stopped recording (or the scripts stopped archiving) at the same time.
They both received there data from the same station - via Meteobridge.
Is it possible that the archiving script or scripts (which is/are ?) got stuck due to having received "incompatible" data before ?
Maybe some cache data to be deleted ? If so, which ones ?
the template says the station is offline, but that's not correct
meteotemplateLive.txt, apiLog.txt, apiCache.txt, apiReqLog.txt get regularly updated and the gauges show the current sensor values
only the database doesn't get updated anymore ...

I have meanwhile switched on php error logging on my website - waiting to see what that gives (if anything)...
