Updating Coppermine to cpg1.5.48 Used old config file and moved over Albums into new folder - ran upgrade.php and was presented with the critical error.
No other instances of coppermine (I have five total photo albums online) had this issue when I ran the installer - just this last update.
Any ideas on how to resolve this issue - I have reloaded and repeated the process with the same result.
Do you have a backup of your database?
Phil - I do have backups for the database
Drop me a PM and I will get some credentials offyou to take a look.
Chickenman sent me a copy of his database and indeed, the anonymous row was missing from the usergroups table. I can only speculate why it was missing. I created a sql file to correct this and he has now upgraded his site.
