XF 1.5 IPN warning from Paypal


Just started receiving these from Paypal

Paypal said:
lease check your server that handles PayPal Instant Payment Notifications (IPN). Instant Payment Notifications sent to the following URL(s) are failing:


If you do not recognize this URL, you may be using a service provider that is using IPN on your behalf. Please contact your service provider with the above information. If this problem continues, IPNs may be disabled for your account.
I've looked in the transaction log & this is whats showing

Transaction log said:
Information: No txn_id. No action to take.
Unknown Account

Only log entries that involve a successful payment will be attached to a user and user upgrade.

Unknown Upgrade
Any idea whats causing this?

Did you move your forum from the forum directory to the route?

If a transaction is associated with the old URL, it will continue calling back to that URL even if you change the default value. If you used to have the forum in /forum, this could be the case and thus ideally you'd want to do some .htaccess redirects to ensure callbacks to the old URL get processed correctly.


I did move my forum Mike. Everything else seems to be working OK. I'm still a novice at coding stuff so would something like

Redirect /forum/payment_callback.php http://www.southeastcountiesbikers.co.uk/payment_callback.php
be correct?
