 * Hello,
 * I just tried to install this plugin on a subfolder (new site being created) and
   it installed, but would not activate.
    This is the error message
 * Plugin could not be activated because it triggered a fatal error.
    Parse error:
   syntax error, unexpected ‘[‘, expecting ‘)’ in /home/xxxxxxx/public_html/xxxxxxxxx.
   com/2017/wp-content/plugins/security-antivirus-firewall/extensions/malware-scanner/
   wptsafExtensionMalwareScannerAjaxHandle.php on line 164
 * Can you tell me how to get this working please or why the error is being caused?
   
   Thanks!

 * I guess that it’s happening because of some PHP version conflict. We’ll check
   it and it’s gonna be fixed in next release. Thank you for your notification and
   sorry for inconvenience.
