This plugin was born out of a very simple need. Back in the day, when the wpautop filter was really sucky, I got annoyed and turned it off for my <a href="http://blog.bigsmoke.us/" rel="nofollow ugc">blog</a>. However, years later, me (but mostly my co-author, Halfgaar) got equally annoyed by having to manually type in all the angle brackets. I wanted to turn on the filter again, but I didn’t want this to affect all my old posts. Hence this plugin. See <a href="http://blog.bigsmoke.us/2010/12/09/wpautop" rel="nofollow ugc">this blog post</a> for more history.

wpautop control

Adds a global setting to turn the wpautop filter on and off. It also allows you to override this default for any post by adding a wpautop custom field …

Note: This plugin does not support the block editor but should continue to work without issue when using it with custom post types and the <a href="https://wordpress.org/plugins/classic-editor/" rel="ugc">Classic Editor Plugin</a>.
Before WordPress displays a post’s content, the content gets passed through multiple filters to ensure that it safely appears how you enter it within the editor.
One of these filters is <a href="https://codex.wordpress.org/Function_Reference/wpautop" title="wpautop" rel="nofollow ugc">wpautop</a>, which replaces double line breaks with <code></code> tags, and single line breaks with <code> </code> tags. However, this filter sometimes causes issues when you are inputting a lot of HTML markup in the post editor.
This plugin displays a checkbox in the publish meta box of the post edit screen that disables the <a href="https://codex.wordpress.org/Function_Reference/wpautop" title="wpautop" rel="nofollow ugc">wpautop</a> filter for that post.
Also adds a ‘wpautop’, or ‘no-wpautop’ class to the post_class filter to help with CSS styling.
