    Hello! Our client is currently using this plugin (Version 4.0.14) and received a PayPal notice about the possible disruption of service due to the PayPal TLS 1.2 and HTTP/1.1 upgrade. I wanted to check if the latest version of the plugin (Version 4.0.20) would indeed work after this takes effect (June 30th).

    Any information on the above would be much appreciated!

    It should, but you never really know. PayPal and your hosting provider introduce many variables.

    I got this answer from Paypal: “…we see a non compliant TLS version on your Script and a source ip address of – IPN url

    David, I need help to make sure paypal is seeing: plugins/seamless-donations/pay/paypalstd-ipn.php (I think) instead, buy not sure how to do this. I have access to the file manager on the server but don’t want to delete anything important. Please help!





    I have the same problem, I received a paypal email :

    We have tried to contact you to inform you of an urgent problem that now requires your immediate attention. Effective June 26, 2018, PayPal will make changes that may affect your ability to accept PayPal transactions, process credit card payments with PayPal, or access money from your PayPal Business Account.

    Our records indicate that your PayPal integration uses an old encryption protocol. Therefore, you must perform the following actions immediately to upgrade your integrations by observing the TLS 1.2 cryptographic protocol before June 26, 2018.

    what to do ?




    If is helps, we got the message as well from paypal

    PayPal is upgrading the protocols used to secure all external connections made to our systems. Transport Layer Security version 1.2 (TLS 1.2) and Hypertext Transfer Protocol version 1.1 (HTTP/1.1) will become mandatory for communication with PayPal in 2018.

    Is your script ready for this?

    Thanks as always!

    My client is also getting the (TLS 1.2) and Hypertext Transfer Protocol version 1.1 (HTTP/1.1) warning message.

    What are we supposed to do to make sure Seamless Donations will continue to work?



    Has this been resolved I have a client locked out of Paypal , hosting service is all compliant is the plugin?

    To ensure the security of our systems and adhere to industry best practices, PayPal is updating its services to require TLS 1.2 for all HTTPS connections. At this time, PayPal will also require HTTP/1.1 for all connections.




    Hi, I also got the same message from Pypal – “Your account was limited for failing to upgrade your encryption protocols to Transport Layer Security (TLS) 1.2. You will not be able to move money out of your PayPal account until you make the required update.”

    I checked the issue against Godaddy and the confirmed that my hosting plan supports (TLS) 1.2.

    So I supposed that this is due to seamless plugin because on my other sites with the standart Paypal buttons I didn`t recieve warning from Paypal.


    Roger Sparks

    Can we please have an answer on this issue? I will understand if we need to switch from Seamless Donations to something else, but please don’t leave us hanging with no answer.

    Is there anyone supporting this plugin any more?

    > Is there anyone supporting this plugin any more?

    Not as often as I’d like. Seamless Donations is TLS1.2 compatible, but your hosting provider needs to be able to provide the necessary SSL software. If their SSL versions are out of date, there’s nothing the plugin can do.




    I had the same TLS 1.2 problem despite the fact that I had the proper version of curl installed on the system. Turns out there was some sort of problem with http -> https redirects and a mixup with the deprecated IPN being used (even though I never configured that IPN in PayPal!) Not sure why the behavior was happening, but I was able to work around it. See the following post for my resolution, YMMV:



    Hi David,

    Same problem for me.
    After checking with my hosting provider, everything is ok from this side.
    We’ve got all the same problem, so i assume really the problem come from your Seamless Donation plugin.
    You say Seamless Donation is TLS1.2 compatible, ok, but it looks there is another problem:
    As John Doane said, it looks you’ve got a problem in the dgx-donate-paypalstd-ipn.php file.
    Here the full explaination of paypal changes :
    I think the problem with seamless donation is coming from here :

    Thanks for your help, for all of us the paypal account is blocked now, it’s of course a big problem.

    The dgxdonate IPN file was deprecated more than two years ago. Don’t use it.

    Adding https support to Seamless Donations 4.0.16



    I am also having problems with PayPal as of 7/1/2018. While my site can still collect donations, we cannot transfer money from our PayPal account to our bank account. This is the message from PayPal: Your account access is limited. Your PayPal integration does not meet TLS 1.2 PCI encryption protocols. Upgrade your PayPal integration to TLS 1.2.

    This message appears on the Settings page of Seamless Donations: Congratulations! Your site appears compatible with PayPal’s requirements. cURL: 7.60.0, SSL: OpenSSL/1.0.2o, HTTPS: responds

    Our site is hosted on BlueHost and I’ve contacted them several times regarding this issue. Each tech I’ve talked to says that the host and our site is compliant.

    I am using version 4.0.20 of Seamless Donations and have the PayPal IPN URL set to (In case it matters, there is a line that says PayPal IPN URL (old)

    Please note I’m not a programmer, just someone that has set up a website for a small charity using WordPress. Up until 7/1/2018, Seamless Donations has worked perfectly for our site!
