PHP 7 Support
WP Statistics is PHP 7 compliant, however some versions of PHP 7 have bugs that can cause issues. One know issue is with PHP 7.0.4 causing memory exhaustion errors, newer versions of PHP 7 do not have this issue.
At this time (August 2016) WP Statistics seems to run fine with PHP 7.0.10, however you may experience issues that we haven’t found yet. If you do, feel free to report it after you’ve confirmed it is not a problem with PHP.
