User Login problem

[French Elvis]

My installation seems to have developed a problem after several weeks of working OK.

Users wanting to login enter username and password as normal. They see a message telling them they have logged in correctly, then, instead of going to their control panel they are asked to login again. No matter how many times they try, the login continues to fail in this way.

The problem seems to clear if I log in to the admin panel, even if I do nothing to reset usernames or passwords. But that only lasts for a short while then it all goes wrong again.

Any advice?

It sounds like a session issue. Can you login to the frontend? or the admin? with no problem?

[French Elvis]

I can login to admin OK but I have had the same front end login problem when using an alias username.

[Eric Barnes]

That is strange. If you have any modules installed can you deactivate all of them and then try?

Also have you made any custom changes that may affect the login?

Normally login problems are site wide.

I have a feeling that one user is somehow causing this problem. Every time he tries to log in from his own computer the problem starts up and then no user can log in successfully.

Then I log back in to admin, and even though I do nothing before logging straight out again, the system returns to normal and any user can log in - except the problem guy!

As soon as he tries again the whole thing goes t*ts up!

Could it be some setting on his machine that's the problem?

Edit: I have no modules installed and have not had the time to make any changes at all since installing 68classifieds

Does that person have a strange username or anything out of the ordinary?

Morning, Eric

No, his username is perfectly normal, and I can log in with his username and password from my computer without upsetting the system.

When he tries from his machine he always fails, and, possibly (though not proven) is the cause of the subsequent general failure.

Hi -- French and Eric -- I remembered reading this some months back. What was the final resolution? Almost the exact same thing is now occuring to me with a particular user (ugh, my best customer) -- when they try to log in with their user name and passwd -- they get returned to the login screen asking again. They are working on a new Toshiba, using IE7 and Vista Home.

Yet I can log in as them, have no problem, have 40 users now & no one has reported this problem. So its gotta be machine specific. Can this be some form of cookies refusal?

I have not as yet hacked the login.php, but I do have a number of mods in place -- but still the immediate finger points to a single user, not site-wide which it would be if there were problems with the code.

So I ask, how was the issue resolved so I can apply it here.

Thanks much

I do not believe this was ever resolved. Could you possibly ask him to turn off any virus scanner or firewall and see if that allows him to login?

Hi Eric
The problem seems to have lied totally with IE. I eased the Firewal, but also added Cookie override control and allow session cookies, which was not checked previously. I believe the latter two the real culprits. Would make sense.
