http://prntscr.com/wdjy1o – with parent theme it is ok
You have a lot of files that are rewritten in your child-theme -> http://prntscr.com/wdjyfl
In the old theme version (you have updated from) all widgets were in theme and we consider that you rewrote some of them in your child-theme. At this moment, due to the new ThemeForest policy, all widgets, post types, and some others files and functions should be in separate plugin for the theme (Royal Core plugin). We made these changes in one of the updates after the old version you had. For now we think you should ask your developer who did those changes in your child-theme to make them compatible with new one. If you need help with the additional customization, submit a customization request to WPKraken team.
Sorry, but additional customization in files is outside the scope of our support.
