Hi @iamkingsleyf
And thank you for using Markup Markdown. 🤝
The information you are looking for is available from the following tutorial :
https://www.markup-markdown.com/wordpress-tutorials/setting-custom-post-type/
You should be able to disable the editor with the default posts / pages with the following snippet :
add_action('init', function() {
remove_post_type_support('post', 'markup_markdown');
remove_post_type_support('page', 'markup_markdown');
});
You can either directly edit the functions.php file inside your child theme by yourself if you are familiar with web development, or add the snippet through a plugin like Code Snippets. (I haven’t tested them all by the way neither is an affiliate)
Feel free to test and tell me if that works for you 🤲
Activating other plugins somehow turns it backon for post and pages.
This is the code we are using, for some reason the editor does not disable for normal post and pages...
/**
* Remove Markup Markdown support from standard post and page post types.
*
* KSM INTERNAL NOTE: Markup Markdown automatically adds support to ALL public post types.
* We only want Markdown editing for IDB custom post types (idb_movie, idb_tv_show, idb_game, idb_spec, idb_book).
* This filter removes support from the default 'post' and 'page' types so they continue using Gutenberg.
*
* ISSUE: Markup Markdown re-adds support when plugins activate/deactivate or post types re-register.
* SOLUTION: Use multiple approaches - remove support AND filter the support check to ensure it stays disabled.
*
* @since 7.29.0
* @since 7.32.4 - Enhanced to prevent re-activation on plugin activation/deactivation
* @since 7.32.5 - Added filter-based approach to intercept support checks
