Suddenly, I can't access the admin panel of a site I created. I am fronted with a blank, white screen. Doesn't seem to matter if I go direct to wp-admin/index.php, admin.php, wp-login.php (which lets me login but to a blank page).
I tried reloading all of the site pages. Checked the host (my other WP installation works fine). I haven't made any changes lately, in fact I accessed and added some pics a few weeks ago just fine.
Anyone have any thoughts? It's a client site and I'm getting desperate!
