I can’t install the plugin, the plugin is displayed incorrectly

Please temporarily enable the WordPress Debug Mode. Edit your wp-config.php and set the constants WP_DEBUG and WP_DEBUG_LOG to true and try
it again. When the plugin triggers an error, WordPress will log the error to the log file /wp-content/debug.log. Please check this file for errors. When done, don’t forget to turn off
the WordPress debug mode by setting the two constants WP_DEBUG and WP_DEBUG_LOG back to false.

I get a white screen when opening …

Most of the time a white screen means a PHP error. Because PHP won’t show error messages on default for security reasons, the page is white. Please turn on the WordPress Debug Mode to turn on PHP error messages (see previous answer).
