This is your clue...  Do exactly what it says...

At a guess, I'd say you've loaded the wcfxs module before wcfxo.  This 
will push your existing X100P interfaces out to channels 3 and 4.  Either 
change your zaptel.conf to suit, or load wcfxo prior to wcfxs to have your 
FXO cards appear where they used to.

Cheers,
