Call script to log last_activity from custom theme not using wp_head()

Hi all,

I have taken over the development of an existing site that runs WP3.3.1 and uses BP1.5.5.

The previous developer used the default BP theme to create a custom theme, which worked fine.

I now have the task of implementing the BP members page but have come across a problem. The previous developer didnt call the wp_head() function as he wanted to include his own specific document header contents. However, as this isnt called the last_activity is not updated for each user when they login and navigate round the site.

I cant simply include it into the custom theme so was wondering, how do I invoke the function that adds the last_activity to the wp_usermeta DB table?

Any pointers would be much appreciated.

Best regards,
Kris…
