Plugin Doesn't Work

Hi, I installed the plugin and when I try to upload a photo, I get the following error. Any clue as to what the problem might be? Thanks!

Fatal error: Call to undefined function bp_activity_update_meta() in /home/content/83/9879983/html/sites/expert-hub_com/wp-content/plugins/buddypress-media/includes/bp-media-class-wordpress.php on line 209

Seems like you have disabled Activity Component in the BuddyPress, our plugin BuddyPress Media currently works only in integration with the Activity Component, so enable the Activity Component to use this plugin.
