[SOLVED] Failed to initialize plugin: pfcbutton

Its been a while I have seen the error and did not had the time to figure out the issue.

Now I finally got time to dig into the code to fix the error

Failed to initialize plugin: pfcbutton
This error occurs when you are using the Classic editor (tinymce) as part of the Gutenberg blocks inside Posts or pages.

Reason:
Inside post-from-category.php on line 598 it uses

add_action ( 'after_wp_tiny_mce', 'pfc_tinymce_custom_vars' );

which not not triggered correctly anymore.

Details: https://developer.ww.wp.xz.cn/reference/hooks/after_wp_tiny_mce/

Workaround:

To workaround this, replace the line 598 with:

add_action ( 'admin_head', 'pfc_tinymce_custom_vars' );

Or add the below code into the functions.php of your current active theme:

add_action('admin_head', 'pfc_tinymce_custom_vars');
