Earlier this year, we shared information on upcoming requirements for using PayPal APIs.
In this post, I’ll update the status of those changes for PayPal and for other gateways and introduce a plugin we’ve developed to help site owners navigate through the required changes.
The dreaded “undefined function” error is a common PHP error that comes up when developing in PHP. We see it specifically come up when using custom code gists from this site.
This post will describe why this error comes up, how to debug it, troubleshooting a whitescreen, and how to avoid the error when writing code of your own. You’ll learn how to test if a certain function or plugin is active before using that function or a feature of that plugin.
PayPal has announced several security updates set to roll out in 2016 which will impact sites using PayPal gateways. This post covers the TLS 1.2 and HTTP/1.1 upgrade scheduled for June 17, 2016. If all actors involved (your host, WordPress, Paid Memberships Pro, and PayPal) update before June (we plan to), you should experience no disruption in your service. However, if you are using the PayPal sandbox environment now or otherwise want to make sure your host and website are ready, please review the content below.
We’ve outlined the steps to take now to ensure compatibility and avoid a disruption of service.
WordPress and Paid Memberships Pro use a system called WP Cron to schedule events like the scripts that PMPro uses to manage membership expirations and queue up “expiring soon” emails.
This post covers a few options to send email to your members list. There are many options for communicating with members via email. Your selection from the options below depends on the list size, email tracking needs and your preferences for automation vs. customization.
We occasionally hear that a customer cannot complete checkout on their site using a valid credit card. The card is declined at checkout, or the card is declined when a recurring payment is processed. In some cases, the site owner can process the card directly through the virtual terminal, so its clear the card is valid. So why is the payment gateway rejecting the card?
Our plugin filters your members-only content using WordPress’ the_content template tag. Occasionally, certain themes and plugin elements also filter on this template tag, which can result in improper/unexpected members-only content filtering. The code recipe below can help resolve this by running the PMPro filter later.
If you’re using PayPal as a gateway on your membership site, below is some information about a September 2015 update to require SHA-256 Compliance. This affects all sites using PayPal for Instant Payment Notification (IPN) on a non SHA-256 compliant server.
It is very likely that your hosting company or server has already been updated to support these new security requirements. However, if you are using an SSL certificate on your site (and especially if it was installed more than a few months ago), you may need to have your certificate reissued.
Read on for more details on how to test your SSL certificate and server and what to do.
The “SSL Seal Code” admin setting allows you to display information related to your site’s security on the Membership Checkout page. It provides users with a way to validate your site’s SSL Certificate or relationship with other security partners for increased peace of mind when using your checkout forms.
This post covers how to add content to that field to display alongside the “Payment Information” section of Membership Checkout.
I blogged previously about using wpMandrill to get delivery, bounce, and click rates on WordPress email. We’ve found that using this method in combination with existing WordPress and PMPro email filters can occasionally break the password reset emails. The code recipe below solves this issue….
