I get a 500 Internal Server Error on and off when I try to visit my site or login. Some days, it's no problem, other days, it's completely down. Sometimes I can see the site but I can't login. Sometimes I can login but I can't see the site.
Error log says: PHP Warning: Invalid argument supplied for foreach() in /hermes/web01c/b1289/moo.emrivermodelcom/wp-content/themes/atahualpa/functions/bfa_ata_admin.php on line 459
I'm running the most recent versions of WP and Atahualpa (with all bug fixes, too). I've disabled all plugins (didn't help). Htaccess file doesn't seem to be corrupted, either.
I don't know php. Do I just need to find someone who does? Or is there some fix for this that I can do myself?
