SMF session bug!!! suggest me something, please

Ok, here is a problem. I have a forum, SMF 1.1.1 (latest version)

I have logged in under administrator.
After some time, when I try to do something, I get a message

Session verification failed. Please try logging out and back in again, and then try again.

But I can't logout, because I get the same messsage. I can continue work, when I delete cookies.

Help me please. Have no time to understand this code and correct. I think, the problem is general and there is solution to fix this problem.

Thank you,
Alex

 

I have explored SMF sources. Seems, the problem in Security.php module, in checkSession function.
Something, like session id from the request and session id from session not equal.
If somebody have experience, let me know please

 

Try this:
Server Settings --> Feature Configuration --> Use database driven sessions

 

I find this problem with this option, or without.

 

Also tried to enable the other cookie settings?
- Enable local storage of cookies
- Use subdomain independent cookies

 

If use second, then I need to turn off local
I try first, will look at result

I think, the problem in difference of lifetime for php session and cookie session, maybe I'm wrong

thank you,
p.s. do you also use SMF?

 

I'm indeed also an SMF user.
Use it on both my forums

 

hm, the problem exists...

 

Weird... Have you asked this on the SMF forum aswell?

You can also try to change the default cookie lifetime lenght and "Seconds before an unused session timeout".
But to be honest I got no idea what the cause of it is.

Have you installed any mods?

 

No mods, default layout
asking about it on SMF community, but still no result
seems, then don't know theirselves

 

I don't know it either to be honest
But it should be related to your cookies for some reason.
Perhaps try to rename them?

 

You think, it will help?
I don't know, how session id is generated, my I think, cookie session id and current php session id are different

 

Well, it must be something on your side I believe.
Am also running 1.1.1, but without any problems.

Have you tried it from other computers?
Care to give me a link to your forum. I'll sign up and see if I get errors aswell.

 

Hm, perhaps,
But the problem is present, and I want to solve it
On my windows apache all is ok
