Hi,
This plugin is tested and works (and is working on several large sites) with WordPress 4.8.1, and PHP versions 5.4 and higher, including PHP 7.
The response above is not an auto-response. Even though I do not provide one-to-one free email support, I took the time to respond personally to your email because your issue was a common error experienced by those with outdated PHP versions:
Parse error: syntax error, unexpected '[' in /wp-content/plugins/zodiacpress/includes/class-zp-birth-report.php on line 141
To be clear, that is not an error with the plugin. That is an incompatibility with older versions of PHP, which are older than version 5.4.
Now, if your site is running on PHP version 5.4 or higher, then you will not experience that error. If you updated your PHP version and still experienced an error, I could try to help if you post here which PHP version you are running and who is your web host so that I can try to investigate the issue. There may be the possibility that you think your PHP version is updated, when it may not have actually been updated on your server.
