I get this error and can't get back to the dashboard or anything... help! please
If you have any advice, I'd greatly appreciate it.

Call to undefined function: home_url() in /home/content/a/n/g/angiebare/html/wp-content/themes/atahualpa/functions/bfa_theme_options.php on line 7

website is: www.angiebare.com -- when I try to go there, I get a white screen with the above error.

Thank you for any instruction you can share.

reverted back to older version for now

what version did you install?
Did you check the BUGFIXs in the 'New Versions & Updates' forum?
