WordPress Fatal error with matomo and php 8.1

Hello @doni3232 You may have an incompatible plugin.
Can you share with us your system report available from the menu Matomo Analytics > Diagnostics ?

And why is the same system running with the same plugins with PHP 7.4?
I can't get to the Matomo menu because I only see the wordpress error message under PHP 8.1.
Here are the plugins used:
accordion-shortcodes
block-bad-queries
custom-fields-gutenberg
easy-fancybox
events-manager
gt3-photo-video-gallery
media-library-assistant
nextend-smart-slider3-pro
updraftplus

Hello @doni3232 Thanks for sending us the list of your plugins. Everything seems to be okay as I don’t see anything from this list Which plugins is Matomo for WordPress known to be not compatible with?

im having the same issue, php 8.1 & 8.2 are going full fatal, aka. white screen of death (backend):

[03-Aug-2023 09:36:16 UTC] PHP Fatal error: Declaration of Piwik\Plugins\WordPress\Logger::emergency($message, array $context = []) must be compatible with Psr\Log\AbstractLogger::emergency(Stringable|string $message, array $context = []): void in […]/wp-content/plugins/matomo/plugins/WordPress/Logger.php on line 95

removing the matomo plugin brings the backend back up.

@doni3232 Thank you for sending a copy of your system check report. This might be a possible bug. I do apologize if we can’t provide a solution for this at the moment. However, I have escalated this and created a new issue in our tracker and you can follow our progress here:?https://github.com/matomo-org/matomo-for-wordpress/issues/831

@jnz31 Sorry to hear that you’re having issue with Matomo for WordPress plugin.

The most common solution to the message?Oops... there was a problem during the request.?is to?setup Auto-Archiving in your Matomo?by following these two steps:
a) Enabling the crontab to run the?core:archive?command and
b) Disabling “Archive reports when viewed from the browser” in the General Settings.

If the error persists, or you’re getting a white screen/page (sometimes called the ‘White screen of death’), it indicates that there is a problem on the server: check in your web server error log file for an error message and send it to us.

I can not find the settings “Archive reports when viewed from the browser” with PHP 7.4, in PHP 8.1 I have a white Screen (in Frontend and Backend).
I can only choose between this:
“Delete old visitor logs and reports”
“Cross-Origin Resource Sharing (CORS) domains”
“Live”
“PrivacyManager”
“TagManager”

@emermatomo i did exactly, what u suggested in ur answer to my post: i had the white screen and i posted the error log. something around logging throws fatal

This worked now with Xampp offline.
I disabled the plugin “WP-Optimize – Clean, Compress, Cache”, slug: wp-optimize.
Unfortunately, I can’t do this online because the e-mail marketing tool “phplist” is still running there and there are errors there.

@doni3232 @jnz31 I do apologize if I can’t provide a solution on this at the moment. Not to worry though, I have created a bug report on GitHub to notify our developers. You can check the bug report on this link: https://github.com/matomo-org/matomo-for-wordpress/issues/831
