LogIn Error using Administrators-1.2.2 and Loaded5

[Petter]

I'm using Administrators-1.2.2 on my shop (standard contrib in Load'ed Five.Zero), and suddenly I get the following error when logging in:

The contribution have been working flawlessly for 7-8 months, but now all of a sudden...

What is really wierd is that if I use the back-button in my browser I'm actually logged in...

Does anyone know what might be causing this?
What would be even better would be some input on how to safely remove this contrib alltogether as I'm the only admin for the store.

Could be an old session that is cached in your browser. Delete all your cookies and browser cache. That should clear it up. Otherwise, you may have to delete the sessions that are stored in the temp directory.

Hi Msasek,

I've tried deleting my cache-folder but to no avail. Are there supposed to be a temp-folder somewhere on the server? Deleting files in my local temp-folder did not help...

This is a server side directory - that you NORMALLY don't have access to or is above the root directory of your web site directory.

Try changing to store sesion in MySQL. In BOTH configure.php files change the 2nd last line:

define('STORE_SESSIONS', ''); // leave empty '' for default handler or set to 'mysql'
to:
define('STORE_SESSIONS', 'mysql'); // leave empty '' for default handler or set to 'mysql'

Good luck

Thnx, I'll give that a try.
