pm not working

my normal pm function is not working properly after installing prillian what can i do

i send it and than the http://blackorwhite.nl/MichaelJackson/phpBB2/privmsg.php
with message only comes up without sending my message it only sends it when i press F5

It looks like I found the cause of the problem if I enter a subject in my pm it does send the pm or email.
If no subject is entered it will not send the message. But no message is coming up that the user should enter a subject to their posts. And I do think it should send a message regardless if it has a subject or not

It looks like on the phpbb support forum it works the same as on my forum (no message being sent without a subject). But they do have a message above it when no subject is entered

Find and remove this line in mods/prillian/prill_common.php:

Code:

Then try it again and see if the error messages appear. This line might be preventing them.

thanx a lot that solved my problem
