PHP7 compatibility

Hi,

Thank you for a wonderful plugin. I’m running it on a site ith PHP version 5.6 and would like to upgrade to PHP 7.0. I used a tool to check compatibility of my plugins and AIOWPS came up as not compatible with PHP 7.0.

The issues seem minor (please see the tool’s output below) and I was wondering if these could be addressed in the next update.

Thank you very much for looking into this 🙂
