blank page syndrome rears its ugly head (fixed)

edit 7 August 2007 later in the day:
At last things are pretty close to working now. What a nightmare!!
~~~~~~~~~~~~~~~~~~~~~~~
I have made some sort of coding errors on my regular theme that is was causing a blank page. So I’ll use one of the default wordpress themes until I figure out WHAT I’ve done wrong…

While the wrong theme is here, the sidebar will make NO sense.

I’m spitting mad that this is suddenly happening now. It’s driving me out of my mind!

edit 7 August 2007:
I’m making progress… now the blank page is gone but the sidebar is STILL messed up.

(Still spitting mad…)
