I set up a server with xoops2.0.6. At first it worked regularly. I imported 130 users to test , and it
still worked regularly. Then I imported more than 3000 users , and I met some problems.
Those are the problems below:
-system ADMIN / preferences / mail setting >> can't show this page..
-system ADMIN / mail to the users >> After submiting it show a white page when send e-mail to more than 400 users..

if anyone has met the same problem, please give me a hande to solve this problem.
thanks.

I've got the same problem...
I'm running 2.07..with 747 users..
