Check the photo. Seems like my website has alot of white space, any ideas why this occurs? It messes up the meta tags etc.

 

It’s normal. This page you are reading now has that as well. To answer the “why”: because it is derived automatically from the forum posts. 
Does it matter? Usually not. Multiple spaces don’t mean anything in HTML. They are ignored. 

The 'description' meta tag has been cleaned up for 4.3 FYI.
