Hi!
Thanks for all the suggestions. Unfortunately we couldn’t figure out the cause of this error. I simply made new facebook page which messenger function works. I consider this topic resolved.
Hi @facebook
The composer was disabled and enabled straight from WordPress, but it didn’t help.
I tried accessing the app management from Facebook Developer’s mode, however the dashboard didn’t have any apps. I am not the one who created company’s facebook page and added messenger plugin to the webpage (that employee has left the company). Could this be the issue? What are the options here?
Thanks!
