Formatting looks OK in input field using CKEditor but does not appear on page when published
If CKEditor is applying the styles correctly but the display of these styles is not showing up after a save, I think you may need to check out the 'Text format' you're using for that CKEditor profile.  It should appear directly under the CKEditor in a drop-down.



After you see which text format you're using, check the configurations of that particular text format here: &lt;your site&gt;/admin/config/content/formats.  

Make sure, when you check the settings, that the 'Limit allowed HTML tags' checkbox isn't checked, which may not allow certain html tags to be displayed.  Look through all the options there and make sure there isn't something else that could be messing up your display.

Let us know if text formats end up being the issue.
