Displays a countdown until the event begins. Specify an event duration time and it will display a different message while the event is happening. After the event is over, the countdown will begin again.
Uses string-to-time (strtotime) formats which can be very simple or very complex.
The widget has many CSS classes to style it with, but it’s been left purposely unstyled so you can format it in whatever way you want. The included recurring-timer-widget.css and recurring-timer-widget.css-example files show how you can move the time and labels around for a custom look. You can customize recurring-timer-widget.css by copying it to your active theme’s folder.
Known issues:
<ul>
<li>It requires a browser refresh before the “next next” event. i.e. If you’re viewing the widget and the timer is set for a daily event, the timer will countdown to today’s event, then countdown to tomorrow’s event. But it will not countdown to the day after tomorrow’s event unless the browser is refreshed.</li>
<li>Events that occur more than once in a 24-hour period have not been tested and may not work.</li>
</ul>

This plugin is deprecated and should not be used for new installations.
PayPal API Subscriptions was built in 2008 using the PayPal NVP (Name-Value Pair) API v52.0, which PayPal has since discontinued in favour of their REST APIs. The plugin also directly handles raw credit card numbers on your server, which creates PCI compliance obligations that most WordPress sites cannot meet.
Recommended alternatives:
<ul>
<li><a href="https://woocommerce.com/products/woocommerce-paypal-payments/" rel="nofollow ugc">WooCommerce + PayPal Payments</a> — modern PayPal integration with Smart Buttons (card data never touches your server)</li>
<li><a href="https://www.memberpress.com/" rel="nofollow ugc">MemberPress</a> — full membership/subscription management with PayPal and Stripe</li>
<li><a href="https://www.paidmembershipspro.com/" rel="nofollow ugc">Paid Memberships Pro</a> — free membership plugin with PayPal support</li>
</ul>
What happens in v1.2.0:
<ul>
<li>Existing <code>[ppsa]</code> shortcodes display a retirement message instead of subscription buttons</li>
<li>An admin notice reminds you to migrate</li>
<li>All PayPal API code, the credit card form, and bundled jQuery have been removed</li>
</ul>

PayPal API Subscriptions

DEPRECATED — This plugin uses the discontinued PayPal NVP API and handles raw credit card data. Please switch to a modern alternative.
