Hi there @chuffeddeal!
Please note that this plugin is not displaying messenger on the website instead of proper installation. It is showing only to the logged in facebook user.
Generally, you can add Messenger to your site from WooCommerce > Facebook, clicking Manage Connection, and clicking Add by Messenger Chat (as explained here).
If the Messenger doesn’t appear for you on the front-end, then that kind of problem is usually caused by either a conflict with your theme or with another plugin.
?
The best way to determine this is to:
- Temporarily switch your theme to Storefront
- Disable all plugins except for WooCommerce
- Repeat the action that is causing the problem
If you’re not seeing the same problem after completing the conflict test, then you know the problem was with the plugins and/or theme you deactivated. To figure out which plugin is causing the problem, reactivate your other plugins one by one, testing after each, until you find the one causing conflict. You can find a more detailed explanation on how to do a conflict test here.
I hope that’s helpful and points you in the right direction. Let us know if you have more questions.
Cheers!
