This is just a quick, short post about some recent issues people are reporting with the post and page editor at wordpress.COM, but it also applies to self-hosted blogs using the software from wordpress.ORG.
If you are having problems getting a blank line between paragraphs in the visual editor, it might be something as simple as the editor not properly coding the paragraphs. In other words, somehow the formatting got changed to something other than “paragraph.”
First, make certain you have the lower second row of icons showing in your editor. If you do not, then click the “kitchen sink” icon at the end of the top row of icons (square with several lines of dots).
Now, look in the lower left corner border area of the editor content window. If all is right, you should see something similar to the image at left: “Path: p” (click for full-sized view). If you see anything that doesn’t contain “p” (such as div), then the editor is not set for standard paragraph spacing and that is why you are not getting any blank lines between the paragraphs. How did this happen? That is a million dollar question with no real answer, but give the following solution a try when you lose the blank line between paragraphs.
With all the text in the post or page selected (highlighted) go to the style pulldown at the left end of the lower tool bar (image at left) and select “Paragraph” from the pulldown. Your blank lines between paragraphs should magically appear and from that point forward, you should be alright—until the next time it happens, and it probably will. Just remember this solution. It has always fixed the issue for me.
