[Serusers] Cant restart SER after I edit the 'ser.cfg'

[Bruce Ferrell]

I have a similar problem:

Following errors:

Maxfwd module- initializing
  0(28433) mod_init(): Database connection opened successfuly
acc - initializing
voicemail - initializing
  0(0) submit_query(): Unknown column 'user_agent' in 'field list'
  0(0) submit_query(): Error while submitting query
  0(0) preload_udomain(): Error while doing db_query
  0(0) register_udomain(): Error while preloading domain 'aliases'
  0(0) domain_fixup(): Error while registering domain
ERROR: error ffffffff while trying to fix configuration


I don't see where the columns for the query are defined in the config. 
The change I made (and changed back) was to point SER at different DB 
machine.
