Strange issue with a single page (white text; uneditable)

I have a single page on my blog that is giving me fits. Out of nowhere all of the text is white under ‘Visual’ and I am unable to select the ‘html’ tab at all. The page has no fancy html code that could be causing this. I tried 3 browsers all with the same results. I copied and pasted the code to a new page and it worked perfectly. Upon trying to edit the new page I had no problems at all. As easy as it would be to delete the page and just republish it, I don’t know how to assign the same URL (actual url, not SEO friendly url) and this page is heavily categorized in google due to its nature.

Anyone have any tips on the fix or a solution to republishing it so as not to lose the search position?
