Hi to all.. I've a trouble with xoops..
There are 10 members in my site who can't post anything in forum or in any comments module (like comments in news module, in polls module).. before this happened, they can do normally..
Not all of the members, but just 10 members of my site having a problem like this.
I didn't change any configuration at all in the administration menu, but it happened suddenly.

This message appear when they post something :
"Could not insert forum post"
Besides that they want to register to have a new account, but it can't too.. the message :
"Could not register new user"

NOTE : All these 10 members can login into the site like usuall, but they can't post anything..

I don't know again what i should do to help this 10 members..
My site is new, & i have about 60 members, 10 of them is like this.. OMG !!

Please someone help me..
I really2 need your help.
Thanks before..

xoops version?
hacks?
modules that fail?
php debug?
server details?

Cant really help without these. Check template_c, cache are writeable as a first start.

xoops-2.0.15
hacks? i don't get it with this..
there is no fail with module installation
php debug? i don't know too..
server details? php 4.3.4, apache, mysql

about template_c, it's already writeable from the 1st time..
the problem is, this happened suddenly..
b4 this happened, there is no problem with this 10 members..
The others 50 members still have no problem, but these 10 members have a problem like this suddenly.

their firewall maybe blocking http headers or whatever firewall, anti-spyware package they use.

But why the others 50 members have no problem at all..??
just this 10 members ??

I've checked on my server, they said there is no problem with the firewall..
