One more issue that I found out about was.
When this plugin is enabled, insert more tag automatically hides when you switch between Visual and Text tabs.
Tag <!–more–> is intact when you check the Text tab, but its hidden in the Visual tab.
After disabling the plugin it is visible.

And you have both the above mentioned plugins enabled ?
And whats your setting for Configure New Line Behavior Per Post Type under Settings > Writing

Hi Yammy,

I am using Preserved HTML Editor Marup as well as PS Disable Auto Formatting plugin in my site.
The code to remove_filter that you have mentioned has to be there in function.php or not ?
