I JUST INSTALLED Buddypress in my blog. even though the captionsays the installation was successful, when I go to Activate plugin there is a warning that says: Fatal error: Call to undefined function get_user_meta() in /home/jose1web/public_html/underground/wp-content/plugins/buddypress/bp-forums.php on line 530
What can I do?

== when I go to Activate plugin ==

You mean when you activate BuddyPress plugin? or another plugin?

Sounds like you’re using an older version of WordPress.

Deactivate BuddyPress and upgrade WordPress:
