Page Templates and Line Breaks

One day WordPress will start formatting extra lines as empty
elements or a collection of tags, and suddenly hundreds, if not thousands, of WordPress users will come to the forums asking why they have all these extra lines in their posts, and how can they remove them…

One solution is to place this* on each line you want to create a break for:

 

or some other non-displaying character entity. An extended <pre> element will work just as well. Basically anything which will force WordPress to jump the line.

* When using the visual rich (wysiwyg) editor you’ll probably have to use the Edit HTML source button to insert your code — though as I’m not a user of that editor, I can’t tell you if this will provide a final solution.

there is a plugin to fix this
