Forum login impossible with IE

Hi,
I can only connect to the forum with Firefox but not with IE7 or IE9 !
When I click on the Login button, I have the fields to log-in. When I submit I'm registered, but after a few seconds I'm redirected to the board and I'm not identified.
With IE9 I have the following message :
You have specified an incorrect password. Please check your password and try again. If you continue to have problems please contact the Board Administrator.

Thanks for help. I can only connect from home ;-((

mmm, just tested with ie8, anyone else can test with ie7 or ie9?

.
Just logged-in with IE9 to test.
Worked fine.

I usually use Firefox - which works fine (currently v14.0.1).
Also use Opera - which works fine (currently v12.01).

Try cleaning your cookies then log-in again.
Make sure you are using the WWW like
h##p://www.flexicontent.org/ . . .
not
h##p://flexicontent.org/ . . .

.

I put the www. and cleant my cookies...
But the strange thing is that I'm logout after the redirection to main forum board, after being logged in.
This only at work (firewall, ...) and with my 3G phone.
At home, it's OK

Thank for an idea. Regards
