Plugin disappears

hi @joomstef

can you also add in your wp-config.php file the following line:
define( 'MATOMO_SAFE_MODE', true );
it should let you have the diagnostic page.

Quick additional information.
I uploaded the plugin files again and activated that safe mode.
Here you can find the system report. Hope this helps to find a quick solution:
