I cannot stay Adminintration page ! ver2.2

When I logged in as admin and click "Adminintration," Adminintration page was showed sucessfully. But soon I returned to login page when clicking some items in the menu.  I set read/write permission to directories and a file as explained in the manual for ver2.2. How can I solve this problem?

Thank you in advance.

I, too, am having the same problem. When I click to change like lets say, "General Settings," I get logged out and returned back to the log in page.

Sorry for double-post.

But I found the solution to this post. Maybe I should start reading posts more often.

So after tinkering with the information from the above thread, I am still being redirected back to my login page.

I asked a series of questions on this topic https://www.nopcommerce.com/boards/t/13267/staying-login-issues.aspx#54980 can you answer them as well oshtu? Thanks!

Thank you for your reply.

My answers are as follows
1. What database store did you choose? SqlCe or SqlServer?
SqlServer

2. How did you install the application? From source?
From source

3. Where did you get the project from? Download it from codeplex, used a tool, somewhere else.
Download it from codeplex

4. How are you running the application? IIS or Visual Studio.
IIS.

This problem has not been found in the local Web Server and SqlServer.  When I uploaded the progrrams to a remote server, I was not able to stay Administration page and was required to login again.  I think it relates to certain file or directory permissions  because I could open  Administration page "once."

Additional Info

I changed the database from SQL Server to SQL ServerCompact. But I got the same problem.
So the difference between SQL Server and SQL ServerCompact is not related to this problem.
When I click a specific menu item in an administrator page, the target controller (in MVC) is changed. During that time, it seems that auth info is not correctly succeeded.

I still need help!
Thank you.

Additional Info 2

I changed the administrator email address from "[email protected]" to mine. Does it give any effect to authorization and authentification ?  Because I failed to install NopCommerce ver2.1 by changing the administrator email address.  When  I used the default admin name "[email protected],"  the installation was completed.

I still need help.
Thank you.

Additional Info 3

I have changed NopCommerce version from 2.2 to 2.3. But the problem continues to be unsolved.

If anyone has any hint, please tell me.

Thank you.

Sorry for not getting back to you. I'm on vacation and away from an environment where I can try and reproduce the problem. I won't be back in town until Monday. I am watching these topics though.

Try setting a machine key in web.config. It'll solve the issue of logging-out
