PayPal Subscribe Error: DEPRECATED_PARAM_MODIFY - with PayPal gatey

3 years 10 months ago #318935 by inelia
Hello,

When I try to use the PayPal subscribe button to set up a payment for my plans I get a simple PayPal page saying:

"Things don't appear to be working at the moment. Please try again later."

And the URL is this:

www.paypal.com/webapps/shoppingcart/error?flowlogging_id=2c2c73a05c6fc&code=DEPRECATED_PARAM_MODIFY

The only hit as to what the issue may be is the DEPRECATED_PARAM_MODIFY

This seems to have started this morning. I have updated to the latest CB Subs and Community Builder plugin, but I still get the same error.

Is it just me, or did PayPal deprecated something in their code so PayPal subscriptions are not working anymore?

The Gateway I am using I "PayPal Gateway"

If it helps here the payment form generated by the plugin:

Just by poking around I have discovered that if I remove the line:

components\com_comprofiler\plugin\user\plug_cbpaidsubscriptions\processors\paypal\cbpaidsubscriptions.paypal.php:266 then things start to work again.

That is the only "modify" variable that could be linked to the error message I get from PayPal and seems to have done the trick

Strange, according to their documentation values of 1 and 2 for modify are deprecated, but we send a value of 0 which isn't deprecated.

developer.paypal.com/docs/paypal-payments-standard/integration-guide/Appx-websitestandard-htmlvariables/#deprecated-variables

Only values of 1 and 2 should respond with an error. It's possible this was a recent change on PayPals end or even just a temporary issue, but I see no official notice that it should be removed so I'm not sure what to suggest. Have you tried contacting PayPal?

I have, but I am being passed around to various people, and each one is not understanding what the problem is :) So far no luck with getting any official info.

I finally reached tech support at PayPal so I could ask my question. I will post here their official reply. In the mean time, the work around is to comment out that variable.

Questions: Since that "modify" variable is now deprecated and optional, why do you still keep it around in the code and not remove it altogether?
