I can't access my buddypress wp-admin as admin after upgrade, accidental click on deactivate...
After re-activation, wp-admin doesn't access anymore! Please help

I get 500 timeout

I know this is buddypress problem because I have moved "buddypress" folder from wp-content/plugins and only doing so, i can access wp-admin dashboard as admin.

Help
