Hi,
I have tried the following:
1) Deleting the app on my FB account.
2) Revoking access to my FB page and reassigning again.
3) Clearing the cache.
4) Deleting the plugin on WordPress and reinstalling again.
5) Trying to connect using another FB account with full admin rights to my FB page.
However I’m still unable to connect my page.
I have also “exclude Trustindex’s JS file: https://cdn.trustindex.io/loader.js” from my cache plugin.
I’m using WP Fastest Cache.
Kindly advise and thank you for your patience.
