I am having the same issue and this solution above does not seem to work for me.
Here is what I did:
1. Created a child theme for customizr
2. Included a style.css file and a custom-page.php file in the child directory
3. Moved the do_action( ‘__fp_block’ ); line all the way down above the get_footer() line as in the code above from macohen85
4. Activated the child theme
What else do I need to do? Not sure what you mean by “clicked update in the wp-admin area”. Where do I select my custom template and click update?
Apologize if this is a basic question – I am new to all this….
