What the H*ll Happend? Missing Line Breaks

That seems odd! How frustrating, huh…

You should probably contact your theme developer for support on this issue:

Though I’m not 100% sure it is theme related.

To test this, you can try and change to a wordpress theme like 2014 or 2013 and see if the spacing go back to normal.

Right now it is stripping out all of the <p> tags and using ” ” instead.

Think , I found it..

It has something to do with the Jetpack plug in.

see option: Custom Content Types

If you have existing content that isn't displaying correctly with this plugin enabled, you should use the 'Fix ...' buttons below. This will modify the content in the database with wpautop, including past revisions.

Fixing a content type multiple times should be harmless as WordPress does this by default. Content that you have modified via the editor after the plugin activation date will not be affected. But it is recommended that you fix your existing content soon after enabling the plugin.

So everything is working now?

Seems like it, yeah!
