Hi,
I recently tried to login to my admin, which has been fine for over a year now. I got a weird message about an open session, but couldn't figure it out. I hadn't upgraded for a long time, so I decided I'd better try that.

I was going along fine with zc-install (configure files were writable) until I hit the button for Update Database Now. I got this:

1062 Duplicate entry '30' for key 1
in:
[INSERT INTO configuration_group VALUES (30, 'EZ-Pages Settings', 'EZ-Pages Settings', 30, '1');]
##################################################__

At the moment, when I try to login to admin or view the catalog, I get this:
Warning: session_start(): open(/mnt/web_k/d09/s29/a000kx29/www/catalog/cache/sess_ecb57d98de0618fd7edd8f31ce1b984f, O_RDWR) failed: Permission denied (13) in /mnt/w0607/d09/s29/b0148571/www/catalog/includes/functions/sessions.php on line 108
1054 Unknown column 'startdate' in 'field list'
in:
[select startdate, counter, session_counter from counter_history where startdate='20070723']

(It had been something about a conflict with line 111).

I'd appreciate any help, as I haven't been able to find anything by searching the forum.

Thank you.
