Problems with automatic Signed In

Hello

some of our members reported me the same problem.

When they make a post and click "send" it ask for SIGN IN (name and psw)
but they are already signed so they must again sign in.
Becuase of that, their posts were clear and must again write a post.

It is really not good and some of them are angry of that. Can you help
me?
What can be the problem? Why the forum asking to sign in again when
they are and also they have checked the box Automatic Sing in...

Is it something with setting of our forum or their firewall?

And second ask for a help. I also noticed, when I am writing a post and
I click a smile icon from the icon list, the message is clear and I need to write
again...

our forum (motorcycle brand community forum):
vstromclub.slovakforum.net


Many thanks for any help,


Slavo
