Pm's not working. Need Help Please!!

[BabyDev]

I am running a phpbb forum (Anubis style) and my pm's are not working. For some odd reason, when you enter a username and submit the pm, it tells you that you need to enter a username. I know for some reason its not seeing the username but I just dont know how to fix it.

 

Any suggestions on what I can do to get this fixed? Also, I may add that I have installed MODS but I dont really see the MODS I have installed interrupting the pm's.

 

Thanks for any help and/or advice I can get.

p.s. I have already been thru all the MODS to make sure I did them correctly and they are all done the way they are supposed to be.
