BC strange issue

Today i turned my bc on and set it to pupil on es server (both slots) ... I was away from home and when i checked it was making pupils properly, when i returned and checked the brutal combo brutes par niveau function it gave the know error with the db etc etc , i went to the bc folder and the was NO db folder in data ... WTF ? How can i get those pupils ?

Whops. I had only twice a database corruption problem (afair message "COULD NOT START THE DATABASE") that required to take an older backup. They were probably caused by some kind of write error while submitting information to the database.
I guess you have had something similar and the consequence of the Apache database corruption was that it somehow erased the folder...
I doubt you will be able to recover it. Try Recuvea to see what happened, but imo best is to use a backup.

Im not sure but i think there wasnt a db folder in the first place when i started pupiling... that means those pups went to junk rite ? oh shit !
