SSL Mixed Content Warning

Affected Generate Press Version is 1.3.29

On my website i noticed a mixed content warning. Looking at the page source i found that there ist a “http://schema.org….” in the Code.

So i scanned the files of the whole installation for that string and found it in your theme on several places.

Here is the list:

wp-content/themes/generatepress/inc/template-tags.php (23,2 KB Fri May 6 06:32:33 2016)

Line Number: 203
sprintf( ‘<span class=”author vcard” itemtype=”http://schema.org/Person&#8221; itemscope=”itemscope” itemprop=”author”>%1$s <span class=”author-name” itemprop=”name”>%4$s</span></span>’,

I will now changing all that to https to see if that solves the problem. Calling https://schema.org on a webbrowser i saw that they are running ssl.
