I think I might have found a fix.
– Make sure the bridge isn’t turned on (this shouldn’t be a problem ?? )
– Remove all the WP PHPBB Bridge widgets from the active widget area
– Navigate away from the widget area for the sake of paranoia and navigate back.
– Put your WP PhpBB Bridge Users widget and any others you use back into their active slots
– Activate the bridge
This seemed to finally do the trick for me. Knock on wood
