The Transaction log for database 'EvolutionCommon' is full due to 'LOG_BACKUP'

SOLVED

Good day, 

We have recently upgraded our client to version 9.20.1.003. 

They can't access the Sage Evolution because of the error below.

The Transaction log for database 'EvolutionCommon' is full due to 'LOG_BACKUP' 

The evolution file space is on 3 terabytes storage. 

Thank you
