Matomo WP Plugin crashes WP hosted by IONOS (Internal Server error)

Dear All,
Managed WordPress by IONOS; after installing and activating the WP Plugin, it appeared that my whole WP site was down (internal server errors).

With some patience and several reloads, I entered the Plugin directory and deactivated the Matomo WP Plugin. Now everything is back to normal.

On the Matomo Forum, I found reports related to WP 6.2 and PHP 8 - IONOS recently upgraded to WP 6.2 and PHP 8, so maybe it’s not a IONOS issue but rather an incompatibility with the current version of those two products.

---

The issues occurred right after activating the Matomo plugin. On the starting page, I saw a warning message (warning about PHP and MySQL - contradicting the diagnosis report below) and managed to copy the diagnosis output:

			  # Errors

• Error MySQLi support: missing (Your PHP cli does not load the MySQLi extension. You might have archiving problems in Matomo but also others problems in your WordPress cron tasks. You should enable this extension)

No source file, test, or entry point is identified. Start by reproducing activation with WordPress 6.2 and the reported PHP 7.4.33 environment, then review the diagnostic output and plugin activation failure; done means the plugin activates without an internal server error and the PHP CLI checks report accurately.
