Meks

This is a simple plugin which automatically hides inactive (orphan) shortcode tags you have used for previous themes and/or plugins. It uses the_content filter to search for shortcode tags which are not active and simply removes them from your post/page content (note the shortode tags won’t be deleted form your content, they will just be removed temporarily on your website frontend). It is a great solution if you want to avoid manual removal of old shortcode tags from your entire content.

Remove Orphan Shortcodes

Any gutenberg block storing an array in block attributes JSON is flagged as a shortcode. As most blocks using JSON attributes also use render_callback and server-side rendering, this causes the block to disappear entirely - broken JSON is hard to parse.

Ergo, don't use this if you also use ACF, because any repeater or relationship field in a block can cause the entire thing to disappear.

Fails with Gutenberg Block array attributes

Quickly remove unused (orphan) shortcode tags from your content.
