How to configure WP Fastest Cache Settings

Reading time: 2 minutes | Difficulty: Beginner

Overview

Are your payment forms not working correctly for logged out users, or only some of the time, with WP Fastest Cache active? Follow the steps below to make sure WP Simple Pay works as expected alongside WP Fastest Cache.

Since WP Simple Pay 4.17.5, payment forms load their data from your site as the page opens, so pages with payment forms can be cached. The only pages to exclude are your payment confirmation pages.

Prerequisites

• WP Simple Pay 4.17.5 or later. On earlier versions, exclude your payment form pages as well.
• The WP Fastest Cache plugin installed and active

Cache Settings

Use Exclude Page to keep your payment confirmation pages out of the cache.

1. In the WP Fastest Cache settings, choose the Exclude tab.
2. Click Add New Rule to open the Exclude Page Wizard.
3. Choose Is Equal To in the dropdown, paste in the slug of your payment confirmation page, and click Save.
4. Repeat for your other confirmation pages.

The WP Fastest Cache documentation lists other ways to exclude pages.

After updating WP Simple Pay to 4.17.5, delete the WP Fastest Cache cache once so every page is rebuilt with the current form code.
