Attempting to activate version 80571aa7ec636053912a37f9425cf9c1e1862c89 on

• WordPress 5.2.2
• PHP 7.3.8

• Alpine Linux 3.10

yielded the following error message:

Plugin could not be activated because it triggered a fatal error.

Fatal error: Cannot use vierbergenlars\LibJs\Object as Object because 'Object' is a special class name in /var/www/ishygddt.xyz/~blog/wp-content/plugins/git-content/vendor/vierbergenlars/php-semver/src/vierbergenlars/SemVer/internal.php on line 7
