<p><strong>This plugin is deprecated and should not be used for new installations.</strong></p>
<p>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.</p>
<p><strong>Recommended alternatives:</strong></p>
<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>
<p><strong>What happens in v1.2.0:</strong></p>
<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>

<p><a href="https://make.wordpress.org/core/handbook/references/php-compatibility-and-wordpress-versions/" rel="nofollow ugc">WordPress is not fully compatible with PHP 8.0-8.5</a>. The remaining known PHP 8.0+ issues are deprecation notices.</p>
<p>The same is related to many popular plugins such as WooCommerce, Jetpack, Gravity Forms, and others. Mainly, they produce deprecation notices from the Action Scheduler library.</p>
<h4>Features</h4>
<ul>
<li>The plugin blocks deprecation notices, user deprecation notices, notices, warnings, user notices, and user warnings.</li>
<li>The list of folders from which errors are blocked can be filtered. This list may specify any WordPress Core, plugin, and theme folders.</li>
<li>Plugin filters out errors from these folders only. Errors produced by other code are not blocked, which helps in debugging user code.</li>
<li>During activation, the plugin installs a mu-plugin <code>kagg-compatibility-error-handler.php</code> into the <code>/wp-content/mu-plugins/</code> folder. It contains the error handler, which loads earlier than any plugin or theme.</li>

KAGG Compatibility

A great plugin that solves a lot of headaches when switching to php8.1

Very helpful from php8.1


Almost all major plugins were not ready to switch to php 8.1: Yoast SEO, Rank Math, Mail Poet, etc. You get a bunch of warnings about deprecation. This plugin allows you to solve this problem by simply enabling it. Simple, fast, comfortable


Great plugin

The plugin blocks error messages of any level from WordPress core, plugins, and themes.
