I’ve done the above and still getting a critical error when the page is redirecting back to WordPress from Facebook after confirming the connection preferences.
I’ve tried getting the Facebook page id by inspecting the page. I can’t find it anywhere else? I can get through the process of logging into Facebook and confirming the page details but now when it tries to connect and redirect back to WordPress I’m getting a blank page with ‘a critical error has occurred’ suggesting a plugin conflict but even with all plugins disabled I’m getting the same error.
