Possibe small compatability issue PHP 7.1

Hi Edgar,

I am currently testing if I can migrate the site to PHP 7.1 as it seems that is time to do it. Currently running on PHP 5.6. I just ran a compatibility check using the Plugin: PHP Compatibility Checker done by WP.
I came up with those results: 3 Errors and 1 Warning.
