Hello, I’m VERY new to WP and BP, and trying to learn as I play. I know slim to nothing about these applications

I’m trying to enable users to create their own blogs. I went through the network setup, and setting up the MultiSite option. When I started making changes to the Network Options page, I noticed the error at the bottom of my user’s page: “Fatal error: Call to undefined function: memory_get_usage() in /home/content/…/wp-content/themes/suffusion/functions/actions.php on line 791.”

I’ve tried looking online and couldn’t find anything related to BP, nor anything I understood. I’m trying to make a social network where users can have their own profiles, blogs, pages, etc. I’m running PHP 4.4.9 with GoDaddy (if any of that helps).
