Session - Can Not Login Either In Fronstore And Backstore

[Guest]

Hi,

 

I have 2 OsCommerces running on a dedicated server.

 

Both worked fine, until today.

Now, neither customers or admins can login.

 

It has probably to due with the server (UNIX) and a setting someone touched.

Can anyone help.

I'm clueless. :'(

 

Thanks,

Dan.
