Hey loiruca
I found the problem and fixed it!
So I was right and wpautop was not being applied to the section content function so you just need to replace this:
if(function_exists('Form_maker_fornt_end_main'))
{
$section_content = Form_maker_fornt_end_main($section_content);
}
echo do_shortcode($section_content);
with this:
$onetoneContent = do_shortcode($section_content);
echo wpautop($onetoneContent , false);
You need to do this in all the section files under the home-sections folder of your child theme.
/wp-content/themes/your-child-theme/home-sections
Hope this helps!
Cheers!
