Advertising conversion export renders Matomo unusable

Stefan_77 · December 17, 2025, 4:00pm

Hello everyone,
I purchased the “Advertising Conversion Export” plugin for my Matomo (WordPress plugin) to use with Google Ads. After activating the plugin, Matomo no longer works.
As soon as it is activated, I get the following error under “Diagnostics”: "Failed to run Matomo system check. You must be logged in to access this functionality. " If I deactivate the plugin, everything works fine.

WordPress outputs the following in the debug log:
Fatal error: Uncaught Exception: Renderer format ‘console’ not valid.

Does anyone have any idea what the problem might be?

Hi there,

according to my colleague, this is a WordPress issue:

github.com/matomo-org/matomo-for-wordpress

Installation fails on LocalWP instances

When trying to install Matomo on (clean) local instances created by [LocalWp](ht…tps://localwp.com/) it will throw an 502 Bad Gateway. After checking the logs we can see that it fails during init: ``` [12-May-2025 15:44:23 UTC] Matomo: Matomo is not yet installed... installing now [12-May-2025 15:44:23 UTC] Matomo: Matomo will now create the database [12-May-2025 15:44:23 UTC] Matomo: Matomo is now creating the config [12-May-2025 15:44:24 UTC] Matomo: Matomo will now trigger an update [12-May-2025 15:44:24 UTC] Matomo: Changed global option version_history: ["5.3.0"] [12-May-2025 15:44:24 UTC] Matomo: Changed global option core_version: 5.3.1 [12-May-2025 15:44:24 UTC] Matomo: Save settings [12-May-2025 15:44:24 UTC] Matomo: Matomo is now syncing blogId 1 [12-May-2025 15:44:24 UTC] Matomo: Matomo site is not known for blog... will create site [12-May-2025 15:44:24 UTC] Matomo: Matomo created site with ID 1 for blog [12-May-2025 15:44:24 UTC] Matomo: Matomo will now sync 1 users [12-May-2025 15:44:24 UTC] Matomo: Matomo is now creating a user for user id 1 with matomo login utomic [12-May-2025 15:44:24 UTC] Matomo: Matomo is now installing the tracker [12-May-2025 15:44:24 UTC] Matomo: Matomo will now init the environment [12-May-2025 15:44:24 UTC] Matomo: Matomo will now init the front controller and install plugins etc ``` [No more logs aftwerards!] Afterwards, the plugin is registered in Wp, but: - The summary page only throws you the following error: `Uncaught Exception: Renderer format 'console' not valid. Try any of the following instead: . in /Users/dominic/Local Sites/matomo-wp-test/app/public/wp-content/plugins/matomo/app/core/API/ApiRenderer.php on line 117` - The reporting page just redirects to /wp-admin - The system report contains the following error: `Error Matomo System Check: Failed to run Matomo system check. (You must be logged in to access this functionality.)` After checking Php Memory and execution limits, DB Limits, and some more I'm not sure what else could be the problem. The plugin also successfully creates the `/wp-content/uploads/matomo` folder, including the `config/config.ini.php` and some more files. Do you guys have any idea what could be the issue? I stumbled on this, as a local clone of one of our sites doesn't work locally anymore, as long as the matomo plugin is installed. In order to track down the issue I tried with a clean WP installation but wasn't even able to install Matomo on instances running in LocalWP. Does the plugin requires any unusual permissions or configs?
