A blank page in your browser often suggests some sort of PHP error. It's often called the "white screen of death". It is usually caused by a buggy plugin or some incompatibility between the plugin, the version of WordPress and/or PHP.

Depending on how you installed the plugin, another possibility is permissions issues. If you installed via the WordPress web UI or via CLI using our helper script, then that should not be an issue. However if you installed via the the wp CLI client or manually by uploading the files to your server, then that's likely the cause. To ensure permissions are correct:

chown -R www-data:www-data /var/www/wordpress
systemctl restart apache2

It may also be worth clearing the cache and cookies from your browser - although I doubt they would cause issues...

If that's not the issue, double check what version of PHP and WordPress the plugin requires. TurnKey comes with PHP 8.2.

If that all checks out, then I suggest double checking the Apache logs for any PHP errors. The Apache logs are found in /var/log/apache2.

If the Apache logs don't help, I suggest that you try enabling debugging on your WordPress server to see what the issue is. Unfortunately I don't have details handy, but a quick google should turn something up (TurnKey is Debian under the hood so instructions for that - or even Ubuntu - should do the job).

If you work it out, it'd be great if you could post back with the solution. If not, please post back with details on how you installed the plugin and once I'm back from holidays (Jan 6th) I'll see if I can reproduce the issue.
