We've had a really high number of recurring contributions this month. I started becoming worried because some of the amounts are quite high. Doing some digging, it appears that everyone who used paypal to register in the past month has a recurring contribution set. I tried to run a test, but the payment wouldn't go through (for some reason civi is deleting the "sandbox" portion of the URL when I click save. Any idea what's happening there?) In any case, the test appears to have recurrence turned on even though I didn't opt for a recurring payment.
Could this be an issue with our payment settings? Or is there a bug in civi? This bug runs a serious risk of breaking our trust with our members.
We changed over to paypal pro at the beginning of the month, so it really seems that this issue is tied to that change. Credit cards entered on the back-end aren't coming up as recurring, but it appears every single transaction entered on the front end includes recurrence. There's no way 100% of users selected this option. As mentioned, my test appears to confirm this, even though I couldn't complete the payment.
We are running Wordpress 4.5.1 and CiviCrm 4.7.6.
