Problem with Paypal IPN Processing

If it’s relevant, the rest of the log is here when I tried again:

Yep, that’s because https://davidsshoes.org/blog4/wp-content/plugins/seamless-donations/dgx-donate-paypalstd-ipn.php isn’t accessible to the Internet. It’s probably a setting your host needs to change. You should be able to paste that into a browser and see a simple string. Yours shows access denied.

–David

I’ve look at it and it shows the following:

content-type: text/plain

Is this what it is supposed to show?

Any idea what setting I’d need to change?

I’m guessing that because I see Access Denied (which is what PayPal will see), but you see text/plain, you’re going to need to change a logged in/logged out setting of some sort.

Not sure what to tell you as to what. That’s usually different based on hosting provider and individual settings.

My hosting provider is Yahoo Small Business. Unfortunately, I don’t have access to the back end yet, so it might be a bit tricky for me.

I’ve just checked that URL again, and now it’s displaying properly. Maybe there was a glitch at the hosting provider. Go ahead and test again and see if the IPN goes through.

No dice. It still shows the same message.

Under recent activity in the paypal sandbox, it shows on both the buyer and the facilitator pages that the transactions were send and received, but the records aren’t sent back to the yahoo page.

Are you still getting this in your log:

Yep, same error message.

On the bright side, I was able to gain access to the back end, so I can now try to work from there.

When I initially tried setting up the online store for add-ons, I ran into a complication in that the hosting provider I used blocked certain kinds of connections. I’m wondering if your hosting provider is blocking these connections to and/or from PayPal.

–David

I know it’s not blocking connections going to paypal, since the transaction histories on both the buyer and facilitator accounts are updated corrected. However, when Paypal attempts to send a message back, that’s where problems come in.

Yep. That’s because this:

https://davidsshoes.org/blog4/wp-content/plugins/seamless-donations/dgx-donate-paypalstd-ipn.php

Is not responding properly. I’m once again getting no result (not an access denied, but nothing). Until that reliably responds, it won’t work with PayPal.

That’s also relatively simple code (at least to the point where you see a response), so if outside viewers can’t see it, it’s probably some sort of hosting issue.

–David

A friend found the caching plugin was caching the donation page. He added the donation page and donation files to the cache ignore list and solved the problem.
