we have had this happen about 30% of the time in the past few months, people pay for subscription and it charges them twice through PayPal.

I will attach subscription and payment basket & pp screen.

I can't figure out where this is coming from but since it has happened frequently (and just started happening recently) I do not feel it's user error. Can you give me any ideas on what to check? I did just update to cb subs 4.0.1 but did not see that as an issue in the changelogs.

Thank you,
Cheryl

Strange, even has 2 different transaction numbers. Maybe they're mashing the button and submitting more than once? CBSubs should be protecting against that by blocking form submit while it's already submitting though. What type of plan is being purchased (subscription, merchandise, or donation) and where (registration or from profile)?

Unfortunately I don't know where from. i just can't imagine all these people are hitting the submit button twice (it has happened a bunch).
Subscription plan (not same plan either we have a few)
Most likely from profile, as i THINK they are mostly renewals.

Also note the duplicate payments are the same payment basket and same Item #, although diff transaction #s in paypal.

Kyle, also the payment is being posted twice in paypal, but his subscription is only valid for the one year.

Please PM backend super administrator login credentials (see signature for link) and will take a look. Am not seeing any issues with double payments in my tests, but should know more after reviewing your CBSubs logs.

Looks like it's possible for this to happen when using the Website Payments Pro API instead of the Payflow implementation. I'm not sure why though. There's no redirect in place to double pay and it blocks duplicate invoices in my tests. Have added a bug ticket and will debug further to see what's going wrong.

Notice for the duplicate payments on your site INVNUM in the request data when reviewing their notifications in CBSubs > Notifications are the same. This is supposed to stop it from paying that same invoice twice. This works fine in my tests, but I'm not sure why the duplicate payment isn't blocked in yours (we of course need to fix it even attempting a duplicate payment). Maybe a missing setting within your Website Payment Pro settings within your account?
