[SOLVED] Error in bfa_header_config.php after migration

Hi,

I have just migrated my site over to Rackspace cloud. Everything loaded fine, db went over without a hitch. DNS records are changed and a ping and tracert shows all in order. But when I access the site, first it is absolutely dog slow (think of access through a 56kbs modem). The site loads OK, but the first thing you notice is that the header image isn't displaying and only shows the alternate text. The second thing that happens is that when I am trying to log in to the WP Admin area it throws me an error "Page not found" and an "oops, you're looking for something that's not here". wp-login.php does exist. Checking the logs I find this error message:

[01-Nov-2009 13:24:06] PHP Warning: array_rand() [function.array-rand]: First argument has to be an array in /mnt/stor2-wc2-dfw1/531252/www.nameofdomain.com/web/content/wp-content/themes/atahualpa/functions/bfa_header_config.php on line 279

Not a clue what's happening as all was beautiful on the old server.

Any help much appreciated.

Cheers
Paul
