Title: WordPress / Self-hostes PHP API / Critical Error Last modified: September 21, 2023 --- # WordPress / Self-hostes PHP API / Critical Error * Resolved [Jan](https://wordpress.org/support/users/locke85/) * (@locke85) * [2 years, 8 months ago](https://wordpress.org/support/topic/wordpress-self-hostes-php-api-critical-error/) * Hi [@braekling](https://wordpress.org/support/users/braekling/), * I’m running Matomo on the same server as the website, hence used the option ( self-hostes PHP API) to connect wp-matomo to the matomo instance. When I click“ save” [this critical error](https://share.zight.com/p9uYjOxD) occurs. * In the WP error log provided these details: * #6 /home/wp/disk/wordpress/wp-content/plugins/wp-piwik/classes/W” while reading upstream, client: 62.216.206.50, server: 60plusconsulting.de, request: “POST / wp-admin/options-general.php?page=wp-piwik/classes/WP_Piwik.php HTTP/2.0”, upstream:“ fastcgi://unix:/var/run/wordpress.php-fpm.sock:”, host: “60plusconsulting.de”, referrer: “[https://60plusconsulting.de/wp-admin/options-general.php?page=wp-piwik%2Fclasses%2FWP_Piwik.php”#5](https://60plusconsulting.de/wp-admin/options-general.php?page=wp-piwik%2Fclasses%2FWP_Piwik.php%22#5)/ home/wp/disk/wordpress/wp-content/plugins/wp-piwik/classes/WP_Piwik.php(1044): WP_Piwik\Request->perform()#4 /home/wp/disk/wordpress/wp-content/plugins/wp-piwik/ classes/WP_Piwik/Request.php(63): WP_Piwik\Request\Php->request()#3 /home/wp/ disk/wordpress/wp-content/plugins/wp-piwik/classes/WP_Piwik/Request/Php.php(18): WP_Piwik\Request\Php->call()#2 /home/wp/disk/wordpress/wp-content/plugins/wp- piwik/classes/WP_Piwik/Request/Php.php(46): Piwik\API\Request->process()#1 /home/ wp/disk/wordpress/wp-content/plugins/matomo/app/core/API/Request.php(282): Piwik\ API\ResponseBuilder->__construct()#0 /home/wp/disk/wordpress/wp-content/plugins/ matomo/app/core/API/ResponseBuilder.php(43): Piwik\API\ApiRenderer::factory() Stack trace:2023/09/21 17:49:56 [error] 2946682#2946682: *704488 FastCGI sent in stderr: “PHP message: PHP Fatal error: Uncaught Exception: Renderer format‘ console’ not valid.

This should not be necessary, Matomo Analytics is intended to be used standalone. * The error message also points to Matomo itself: * ```wp-block-code PHP message: PHP Fatal error: Uncaught Exception: Renderer format ‘console’ not valid. Try any of the following instead: . in /home/wp/disk/wordpress/wp-content/plugins/matomo/app/core/API/ApiRenderer.php:143 ``` * I switched my personal setup to PHP mode and don’t receive any error, maybe [@matomoteam](https://wordpress.org/support/users/matomoteam/) can give a hint what’s wrong here. * Thread Starter [Jan](https://wordpress.org/support/users/locke85/) * (@locke85) * [2 years, 8 months ago](https://wordpress.org/support/topic/wordpress-self-hostes-php-api-critical-error/#post-17085282) * Hi André, * thanks for getting back. I’d love to get the new from [@matomoteam](https://wordpress.org/support/users/matomoteam/) also. * I understood your comment about running both stand-alone. * Why would we want to run both in parallel: I’m migrating different sites from GA to Matomo and most site owners got used to SiteKit from Google which nicely presents relevant stats directly in the WP dashboard. In my research I ran into your plugin which apparently does similar things on the back of Matomo-Analytics. It would be convenient for users not having to navigate into Matomo/ Reports but have everything right there in the dashboard. * That said, I updated Matomo- Analytics to the latest version and tried to connect again: Added the path /wp-content/plugins/matomo/ and switched to PHP mode. The error still occures ;-( * The full path is as follow: [https://domain.de/wp-content/plugins/matomo/app/](https://domain.de/wp-content/plugins/matomo/app/) * Which part of the URL did you use? * Thanks, * Jan - This reply was modified 2 years, 8 months ago by [Jan](https://wordpress.org/support/users/locke85/). * Plugin Author [braekling](https://wordpress.org/support/users/braekling/) * (@braekling) * [2 years, 8 months ago](https://wordpress.org/support/topic/wordpress-self-hostes-php-api-critical-error/#post-17099019) * Hi Jan, * I get why you want to use both together. Just wonder if it would be better to run a standalone Matomo instance beside WordPress instead of an integrated one. * First, if you want to use PHP mode, I would suggest to use a full, absolute path, e.g. `/var/www/yourblog/html/wp-content/...` * Second, did you try HTTP mode? This should definitely work and is less error- prone. * I’m just using a standalone Matomo instance and this is working fine, so sadly I can’t reproduce the issue. Hopefully somebody else or [@matomoteam](https://wordpress.org/support/users/matomoteam/) can check if the combination of both does normally work or if it is a recurring problem with this specific setup. * Plugin Author [Thomas](https://wordpress.org/support/users/tsteur/) * (@tsteur) * [2 years, 8 months ago](https://wordpress.org/support/topic/wordpress-self-hostes-php-api-critical-error/#post-17100457) * [@locke85](https://wordpress.org/support/users/locke85/) I’m not fully sure how WP-Matomo connects to Matomo and what might be the problem there but indeed Connect Matomo is not intended to be used with the full Matomo Analytics plugin. I have a feeling that Matomo is basically loaded twice and it could cause issues. It’s also possible the way it’s loaded that it does not load the correct config file as specified by the Matomo Analytics plugin itself. * By the way the Matomo Analytics plugin also lets you add some reports to the dashboard by clicking on “Matomo -> Summary” and then clicking on the Pin icon. * Thread Starter [Jan](https://wordpress.org/support/users/locke85/) * (@locke85) * [2 years, 8 months ago](https://wordpress.org/support/topic/wordpress-self-hostes-php-api-critical-error/#post-17106466) * Hi Thomas, * thank for you clarification. Especially your advice regarding reports from the summary page is very helpful indeed. * Regards, * Jan Viewing 5 replies - 1 through 5 (of 5 total) The topic ‘WordPress / Self-hostes PHP API / Critical Error’ is closed to new replies. * ![](https://ps.w.org/wp-piwik/assets/icon-256x256.png?rev=3529668) * [Connect Matomo - Analytics Dashboard for WordPress](https://wordpress.org/plugins/wp-piwik/) * [Frequently Asked Questions](https://wordpress.org/plugins/wp-piwik/#faq) * [Support Threads](https://wordpress.org/support/plugin/wp-piwik/) * [Active Topics](https://wordpress.org/support/plugin/wp-piwik/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/wp-piwik/unresolved/) * [Reviews](https://wordpress.org/support/plugin/wp-piwik/reviews/) ## Tags * [installation](https://wordpress.org/support/topic-tag/installation/) * 5 replies * 3 participants * Last reply from: [Jan](https://wordpress.org/support/users/locke85/) * Last activity: [2 years, 8 months ago](https://wordpress.org/support/topic/wordpress-self-hostes-php-api-critical-error/#post-17106466) * Status: resolved
