I just ran in to this same problem. I was finally able to get the featured area to display my HTML (and not just the code) by commenting out line 642 (for featured area 1) in minamaze/admin/main/options.php. This doesn’t put it through the HTML validator. My problem now is that this has to be done in the core files, as when I made the changes in my child theme nothing changes. I’m hoping someone has a fix for that so I don’t lose all of my changes when updating.
I am also having this issue. My changes in the header and footer files in my child theme are showing fine, however the changes to minamaze-child/admin/main/options/02.homepage.php are not showing on my site. I need to be able to add code for widgets in the featured areas so need to remove the calls escaping the HTML, but it is not working. Any suggestions?
I am also looking to sort by the EXIF date/time. Any chance of this being added in?
