Pay Frame We’ve introduced a “payment form” option for easier compliance with PCI requirements. In addition to having a payment form directly integrated in your checkout page, you can use our embedded PayFrame solution to ensure that payment data never touches your website. PayFrame is enabled by default, but you can choose between both options in the plugin settings. Later this year, we’re bringing you the ability to customise the appearance and text content of the PayFrame version. To learn more about the benefits of PayFrame, please visit our FAQ: https://www.paymill.com/en/faq/how-does-paymills-payframe-solution-work Team Officially supported by PAYMILL Developed and maintenanced by straightvisions End of Service Please note, that there is currently no support available for this plugin through it’s creators, the straightvisions GmbH. Reason is that service contract with Paymill has not been renewed, there are currently no updates or patches ordered or planned for this repository. If you have any questions or issues using this plugin, please contact Paymill support directly. Missing a feature? Please use the plugin support forum here on WordPress.org. We will add your wished – if realizable – on our todo list. Please note that we can not give any time estimate for that list or any feature request. Paid Services Nevertheless, feel free to hire the plugin author Matthias Reuter [email protected] if you need to: get a customization get a feature rapidly / on time get a custom WordPress plugin developed to exactly fit your needs. Troubleshooting Error: Paymill can be loaded once only on the same page. This error is self explaining but still might be a bit confusing, as some users will be sure that there is no doubled call of the payment form. There actually is one. For example: you may have the Paybutton widget in a sidebar which is loaded, but hidden by a sidebarmanager. In most cases, some plugins or themes cause this issue, so you may want to try deactivating all plugins except Paymill and try a default theme. Our development site is using Mystile from Woothemes, a free theme which is also certified for WooCommerce compatibility. When logging into Paymill Dashboard, once activated Test Mode is switched back to Live Mode Test Mode and Live Mode are both always active simultaneously. Even if the Dashboard is showing Live Mode upon (re-)login per default, both modes remain active, even when switching to Test Mode and vice versa. How can I log API Requests for Subscription Handling? If you feel subscriptions are not handled as intended, you’ll find logs in directory /wp-content/paymill/lib/debug/ You may need to CHMOD 777 logging files to enable logging.
