[SOLVED] FATAL ERROR in Network Solutions hosted site

After 2 months of operation with no problems, all of a sudden I'm getting a FATAL ERROR with my Network Solutions hosted site, www.yba.com.

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 491520 bytes) in /data/20/1/153/130/1968782/user/2150206/htdocs/www/wp-content/themes/atahualpa/functions/bfa_get_options.php on line 507

I am using ATA version 3.6.5, and I have installed all the patches that were available in August 2011.

Before I call and get the run around at NS I thought I'd ask the guru's here for any ideas.

Thanks in advance

David
