The settings file is in engine/settings.php

Probably best to just delete it and then answer the questions again when you re-visit the main URL.

I'm getting this same error now after FTPing a new start.php file to a mod/plugin. Everything was working fine moments ago. ?

(edit) ...since posting i've checked mySQL database on the server side and the aforementioned settings.php and everything is as it should be...to my knowledge. Grrrr!

*takes bat and ball and goes home to play guitar, and not have elgg headaches*

Thoroughly annoying.

Fixed.

used Cpanel on the server side to 'repair DB' ...what a wonderful program. Looks like my guitar is gonna gather more dust.
