Upgraded to 1.7.1 now won't recognize me as an admin

Hi there,

I upgraded to Elgg. 1.7.1 from 1.6 by following instructions in this file:


I disabled all the plugins (the 'core' ones?? which one is that?)

Now it doesn't recognize admin at all, i have to log in from some place else, and that person had admin permissions, but not after the upgrade.

i need to get back in to enable plugins, but without admin permissions, i can't seem to do it.

anyone know where to look?
