Hi @manesvenom ,
Can you show me what is “reply again and again”? The auto reply function just answer the question 1 by 1. Maybe you can try unsubscribing your FB Page and re-subscribe again from FB App settings. (Sometimes it’s really weird.)
If you want to debug messenger requests you should check log files in “記錄檔” not “Webhooks 紀錄”.
…./plugins/fb2wp-integration-tools/logs/YOURSECRETKEY-request_source.txt
“Webhooks 紀錄” will save post and ratings from FB Page.
