I have been attempting to update Zenphoto from version 1.4.0 to the latest. Set-up appears to go fine, but when I reach the login screen and enter my password I am greeted with the following error:
Fatal error: MySQLi Error: ( INSERT INTO [prefix]administrators (user, valid, rights, lastloggedin, loggedin) VALUES ('dgshepard', '1', '1961345013', '2013-08-28 10:10:58', '2014-03-31 11:15:42') ) failed. MySQLi returned the error Duplicate entry '1-dgshepard' for key 'valid' in /home/sites/oxfordarchitecture.org/public_html/zp-core/functions-db-MySQLi.php on line 78
I'm at a bit of a loss here. I suspect the database columns may have changed between versions. Can anyone advise how to proceed?
