Sorry but...
Even if I'm expecting something else, I'm doing everything you tell me...
I have no .db files... And I've started Anope with UseRDB...
It creates the .db files, send global "we're back", then:
I did "/os update",
it answers me "Don't have permission",
I did "/ns register pass po@po.po",
it anserws "your pass is pass",
I did "/os update",
It answers "Backup in progress" or something like,
I did "/os shutdown",
It answers "Updating databases on shutdown",
I comment "UseRDB",
I restart Anope, and nick.db files has only the nick i've registered before...
And all the other files are clean.
Now I explain you precisely what I did and what I get... If there is an error from me, I apologize, but please tell me where.
Thank you
