Re: WordPress Plugins and Themes with Known Issues

Priority: Low/Medium/High (choose one, remove the other options)

Issue Description:

The MonsterInsights WordPress plugin (https://wordpress.org/plugins/google-analytics-for-wordpress/) is incompatible with Pantheon's edge caching due to its reliance on the PHP_SELF server variable. Pantheon modifies this variable to improve cachability, resulting in all GA4 campaign data being reported as "PANTHEON_STRIPPED." This effectively breaks campaign tracking for users utilizing MonsterInsights on the Pantheon platform, particularly those using WooCommerce integrations.

The customer has reported this issue to MonsterInsights support and was told that Pantheon's edge caching is the root cause and that following Pantheon's recommendations (https://docs.pantheon.io/pantheon_stripped) is the best solution. However, this essentially disables campaign tracking when using MonsterInsights.

This was requested by a customer on a ticket. (https://pantheon.zendesk.com/agent/tickets/970987)

Suggested Resolution

Add a note to the Pantheon documentation (https://docs.pantheon.io/plugins-known-issues) stating that MonsterInsights is not compatible with the Pantheon platform due to this conflict.
Consider exploring potential workarounds or solutions to mitigate this incompatibility, or provide alternative plugin suggestions for GA4 and WooCommerce integration on Pantheon.
