Re: pre tag

You ought not to be modifying anything outside of `wp-content` anyway as this is core and so your changes will get overwritten when WordPress updates. To avoid, you should define a custom function in your theme to alter the default set of tags that are allowed. See [this tutorial](http://theos.in/wordpress/howto-change-list-of-allowed-html-tags-in-wordpress/ “”) for more information.
