[Serusers] acc not writing to mysql

[Decebal Topala]

Hi there i am trying to debug my accounting problem but so far without success. 
I followed the instructions in the module README

Here is the part of my config 

modparam("acc","log_level", 1)
modparam("acc","log_flag", 1)
modparam("acc", "db_flag", 2) 


and in rr part of the script i  have a setflag(1); 
but still i cannot see any updates in the database ???
Any one have an idea why 
Thanks 
Decebal
