Fatal error: Call to undefined function when running advert

Hello, running an ad in the sidebar of Buddy Press Daily gives me this error in Firefox:

Fatal error: Call to undefined function bp_site_name() in /home/one1111/public_html/dev/wp-content/themes/bp-daily/library/components/advert-sidebar.php on line 21

Nothing appears when using Safari.
