Critical site error on Kinsta-hosted sites when activated

[maguijo]

Installing WPGatsby on my Kinsta hosted wordpress site causes the site to "experience a critical error." It traces to line 79 of the file /wp-content/plugins/wp-gatsby/vendor/ircmaxell/random-lib/lib/RandomLib/Source/MicroTime.php.

Error message: Uncaught Error: Call to undefined function RandomLib\Source\getmypid() in /wp-content/plugins/wp-gatsby/vendor/ircmaxell/random-lib/lib/RandomLib/Source/MicroTime.php:79

Kinsta tells me that getmypid() is disabled on their servers for security reasons. That's why the function isn't defined.

Any way to remove that requirement from the plugin?

Are you using PHP 8? This plugin hasn't been updated to work with PHP 8 yet. If your hosting provider allows it, try PHP 7.4.
