BuddyPress.org

We are building a social networking site. And we us Paidmembership Pro along with Sweet Date theme.
Unfortunately when we activate the buddypress plugin the whole site is not loading properly.

this is the link to the website

We are on a dedicated root server and not on a shared hosting.
We have around 100k+ profiles on our account. Everything works fine, just when buddypress is activated the whole site’s functionality is lost.

Looking forward to heard your valuable advice. Can share admin details or logs if necessary.
