A small non-profit contacted me for help with this very same problem, and due to your fix, I was able to get their site working again, so they could sell tickets to their fund-raiser. * I’m very disappointed in Automattic for not fixing this issue. * – Scott * Plugin Author [Konstantin Kovshenin](https://wordpress.org/support/users/kovshenin/) * (@kovshenin) * [10 years ago](https://wordpress.org/support/topic/a-payment-error-has-occured/#post-6852047) * Just a note that turning off sslverify is very dangerous and allows an attacker to spoof your request regardless of HTTPS. * [realdoctorstu](https://wordpress.org/support/users/realdoctorstu/) * (@realdoctorstu) * [10 years ago](https://wordpress.org/support/topic/a-payment-error-has-occured/#post-6852048) * Thanks for the info. What’s the alternative for using the plugin over a non-https site? * Plugin Author [Konstantin Kovshenin](https://wordpress.org/support/users/kovshenin/) * (@kovshenin) * [10 years ago](https://wordpress.org/support/topic/a-payment-error-has-occured/#post-6852049) * Sorry for the confusion, the site itself doesn’t have to be HTTPS, but the requests to the PayPal API do. If SSL verification is not working, something is likely wrong with your hosting environment setup. I recommend you reach out to them for help, but NOT turn off SSL verification. * [sneader](https://wordpress.org/support/users/sneader/) * (@sneader) * [10 years ago](https://wordpress.org/support/topic/a-payment-error-has-occured/#post-6852050) * Hi [@konstantin](https://wordpress.org/support/users/konstantin/). I *am* the web hosting provider. We run very standard cPanel / CentOS 6 installations. What is it, exactly, that we are doing wrong, to cause this problem? * – Scott * Plugin Author [Konstantin Kovshenin](https://wordpress.org/support/users/kovshenin/) * (@kovshenin) * [10 years ago](https://wordpress.org/support/topic/a-payment-error-has-occured/#post-6852051) * [@sneader](https://wordpress.org/support/users/sneader/), an outdated ca-certificates probably. Can you connect to api-3t.paypal.com over port 443 with curl? * [sneader](https://wordpress.org/support/users/sneader/) * (@sneader) * [10 years ago](https://wordpress.org/support/topic/a-payment-error-has-occured/#post-6852052) * Hi Konstantin. I wonder if this problem was already resolved in WordPress. See this bug/defect ticket: * [https://core.trac.wordpress.org/ticket/34935](https://core.trac.wordpress.org/ticket/34935) Certificate bundle with 1024-bit root certificates re-added * In any event, to answer your question, here are two curls: * # curl [https://api-3t.paypal.com](https://api-3t.paypal.com) SOAP-ENV:ClientEnd of file or no input: ‘No such file or directory' * # curl [https://api-3t.paypal.com/nvp](https://api-3t.paypal.com/nvp) ACK=Failure& L_ERRORCODE0=81002&L_SHORTMESSAGE0=Unspecified%20Method&L_LONGMESSAGE0=Method% 20Specified%20is%20not%20Supported&L_SEVERITYCODE0=Error * Plugin Author [Konstantin Kovshenin](https://wordpress.org/support/users/kovshenin/) * (@kovshenin) * [10 years ago](https://wordpress.org/support/topic/a-payment-error-has-occured/#post-6852053) * [@sneader](https://wordpress.org/support/users/sneader/) Yeah, that ticket is just WordPress trying to be nice to outdated software 🙂 But if that point release fixed the issue, then okay, though I still recommend updating libcurl, openssl and ca-certificates. * [sneader](https://wordpress.org/support/users/sneader/) * (@sneader) * [10 years ago](https://wordpress.org/support/topic/a-payment-error-has-occured/#post-6852054) * It might be outdated, but for the tens of thousands of servers (if not hundreds of thousands — cPanel keeps their license counts secret) running CentOS 6 / cPanel, it is what is being provided to us. It’s interesting that WordPress still insists on being backwards compatible to PHP 5.2, which is incredibly out of date and unsupported, but is pushing this type of update. But I disgress… I am pretty sure that the WP bug/defect fix likely solved this issue. I will remove the patch and see how it goes. * Thanks! * – Scott * [realdoctorstu](https://wordpress.org/support/users/realdoctorstu/) * (@realdoctorstu) * [10 years ago](https://wordpress.org/support/topic/a-payment-error-has-occured/#post-6852055) * Hi Scott, * Let me know if you get resolution to the issue. I’m reluctant to remove the patch if it doesn’t work as the site is active, and would need a working alternative if it doesn’t. * Thanks, * Stu Viewing 13 replies - 1 through 13 (of 13 total) The topic ‘A payment error has occured’ is closed to new replies. * ![](https://s.w.org/plugins/geopattern-icon/camptix_aea99d.svg) * [CampTix Event Ticketing](https://wordpress.org/plugins/camptix/) * [Support Threads](https://wordpress.org/support/plugin/camptix/) * [Active Topics](https://wordpress.org/support/plugin/camptix/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/camptix/unresolved/) * [Reviews](https://wordpress.org/support/plugin/camptix/reviews/) * 13 replies * 4 participants * Last reply from: [realdoctorstu](https://wordpress.org/support/users/realdoctorstu/) * Last activity: [10 years ago](https://wordpress.org/support/topic/a-payment-error-has-occured/#post-6852055) * Status: not resolved
