We are using Civi 4.7.29 on Wordpress 4.9.4
Recently we moved our civi install of the root directory oursite.com to a subdomain subdomain.oursite.com.
While we were on the root directory, we were able to take recurring payments with out any problems. Suddenly on the subdomain, we are not able to accept recurring transactions anymore through paypal. It shows the recurring transactions as Pending/Incomplete in civi.
It just occurred to me that the IPN paths might still be hooking to the root directory and need to be changed to the subdomain.
Can someone tell me which folder these IPN hooks are in, so I can review them?
