Hello @planetoffitness,
Previously, we have got some support request that BuddyPress plugin setting “Activity auto-refresh” has some issues with Wp Engine.
You can refer this support ticket for further details: https://buddypress.org/support/topic/buddypress-js-not-loading/
It occurs when the “Activity auto-refresh” option is enabled. You can once try disabling that setting if that works for you.
I am attaching the screenshot for the setting.
Thank you.
