Cannot login, no error

[phobic]

Hi There

I had simpleauth running for a couple of years with no problem, after recently moving it to a new server I'm having a small weird problem - when users try to login the login page just reloads and shows no error message, and does not forward them to the relevant page.

I know the database is working, because if I alter any details in config.php I get a database error in the browser when trying to load any pages. The only other sign that there's a problem is that when I try to use join.php to add a new user, the user does not get added to the database.

Any help greatly appreciated, and many thanks for this awesome free script btw!

Looking at that briefly it looks as though it's a problem with the file permissions on the session files and the webserver can't write to the session files properly. Have a look at the permissions and see if you can change them to allow the webserver user to write to the files.

On my server it's setup so the session file directory is owned by the webserver user, and then inside that directory there's a bunch of webserver session files all with permissions of 600 (ie rw by webserver user only).

Many, MANY thanks!

I was looking into read/write errors for the config.php file (due to wrongly interpreting that error log msg) but actually found this on my host knowledge base:

and the problem is now fixed!

I can't afford much, but have donated via the link on munk.me.uk..

Wow that's very generous of you thanks, I wasn't expecting anything so that's very nice.

Glad it's sorted.
