I am using a plugin named Crayon to format my code in wordpress, however after I have changed config settings, I found the code in my post was dirtied!
It shows like this following: Code Dirtied
What can I do to repair it or what wrong config setting have I made?
I've tried to reset the config and it doesn't work.
- Crypon Version: _2.7.2_beta - 25th April, 2015
- Wordpress Version:WordPress 4.5.3
Thank you for helping

Stop using the plugin, because the square brackets in the shortcode are being interferred with by the square brackets in the output used within the shortcode.
Is there a reason why you can't style it using
<pre>and CSS?
