So I checked out the links but they seem to suggest changing code once you’re logged in but I can’t log in… Any ideas? Herb Miller suggests hacking the core but I have no idea what that entails or what he means by control panel, ftp or something?
Thanks but I don’t even know what a plugin is so I doubt I installed one. For a while before the error screen appeared I could log in but the dashboard was blank apart from one tab – I could not change anything or install anything. I’ll check out your links though and see if they help.
