Hi There,
Thank you for the credentials, after quite some time of investigating this I still don’t get why your sidebar text widget is defaulting to visual editor, resulting to wrap its content in a unnecessary <p>
tag. This <p>
tag is the one that causing those white line issue.
If we can prevent the Wordpress from generating those unnecessary <p>
tags, we might resolve this issue. To do this, please setup a new child theme for X. Then add this on your child theme’s functions.php file
remove_filter( 'the_content', 'wpautop' );
remove_filter( 'the_excerpt', 'wpautop' );
Don’t forget to activate your child theme.
Let us know how it goes,
Cheers!
