Resolving Caching Conflicts with Cookie Notice & Compliance for GDPR / CCPA

Content

If your cookie consent banner disappears, behaves erratically, or causes issues after installing a caching plugin, you're not alone. This is one of the most common support topics for the Cookie Notice & Compliance for GDPR / CCPA plugin. This guide explains why these conflicts happen and provides the most effective solutions to get your site working correctly.

Why Caching Plugins Cause Problems

Caching plugins like W3 Total Cache, WP Rocket, WP Super Cache, and WP Fastest Cache work by saving static HTML copies of your pages. This dramatically speeds up your site by serving those copies instead of processing heavy PHP scripts for every visitor.

The core issue arises because the Cookie Notice plugin uses PHP to check if a user has the cookie_notice_accepted cookie. It then decides whether to output the banner's HTML, CSS, and JavaScript.

If the first visitor to a cached page has already accepted cookies, the caching plugin saves a version of the page without the banner code. Subsequent visitors, including those who have never been to the site, are served this cached version and will never see the banner. The inverse is also true; if the first visitor hasn't accepted, new users might see the banner even after they have accepted. This fundamental conflict between dynamic PHP logic and static caching is the root of most reported issues.

Common Solutions and Workarounds

1. Configure Caching Exclusions (Most Common Fix)

The primary method for compatibility is to exclude the plugin's scripts and styles from being minified, combined, or cached. Based on community reports, adding these exclusions in your caching plugin's settings often resolves the problem.

  • JavaScript Exclusion: /wp-content/plugins/cookie-notice/js/front.min.js
  • CSS Exclusion: /wp-content/plugins/cookie-notice/css/front.min.css
  • General Path Exclusion: /wp-content/plugins/cookie-notice/*

For specific plugins:

  • WP Rocket: Users have reported success by adding the CSS file URL to the "Exclude files from Remove Unused CSS" setting: https://yourwebsite.com/wp-content/plugins/cookie-notice/css/front.min.css?.
  • Autoptimize: If you are using the logging addon, you may need to exclude its inline JavaScript from aggregation by adding a keyword like ginger_logger_url to the JS exclusion list.

2. Enable the Plugin's Caching Compatibility Mode

The Cookie Notice plugin includes a "Caching compatibility" option. When enabled, it applies specific fixes designed to work with various caching plugins. Ensure this setting is turned on in the plugin's configuration. This mode attempts to prevent the plugin's scripts from being incorrectly processed during preloading and other cache generation tasks.

3. Clear Your Cache After Changes

After updating exclusion settings or plugin options, always clear your site's entire cache. This ensures that new, uncached versions of your pages are generated with the correct configuration applied.

4. Advanced: Use a Custom Cookie Name (For Specific Hosts)

Some advanced hosting environments, like Pantheon, have strict cookie caching policies. They may ignore cookies unless they have a specific prefix (e.g., STYXKEY_).

A potential workaround found by users is to use a filter to change the cookie name to something compatible with your host's rules, such as STYXKEY_cookie_notice_accepted. This would require adding custom code to your theme's functions.php file. Note that this is an advanced solution and may not be officially supported by the plugin.

When Problems Persist

If you have tried all the above steps and the conflict remains, the issue may be highly specific to your theme or a unique combination of plugins. In these cases, systematically disabling other plugins and testing with a default theme (like Twenty Twenty-One) can help identify the specific conflict.

Based on numerous user reports, this caching conflict is a known challenge. The 'Cookie Notice & Compliance for GDPR / CCPA' team has implemented compatibility modes and continues to work on solutions, as seen in their update that specifically addressed a JS minify conflict with WP Rocket.
