Failed restore: The file format is wrong.

Post by nethead »


after having problems with our rate table getting created correctly when a new year is created i tried to restore from backups. I had hoteldruid 2.2 installed and i have a couple of backup files matching this version. Everytime i try to restore a backup i got "The file format is wrong."

Ok, so i did upgrade to the current 3.05 version of Hoteldruid, created a new backup and low and behold, when i try to import the freshly created backup file i get "The file format is wrong. Errors: #54b" error again...

I am puzzled.. How can i fix this?

Alternativly, any idea what hinders hoteldruid from correctly migrating the rate table from one year to the next? I did load a pre-covid database from 2019, i get the prompt for importing data into 2023 (using the daily option) but the rates and extra costs fail to be migrated...
