I am having the same problem, and more than once. The page I’m working on now has over 1,000 words on it, but the plugin says “There are 1 words contained in the body copy. This is far too low and should be increased.”
I guess what I really want to know is this – Will SE’s see it the way the plugin does? Or will they be able to recognize that there is text on the page? If it’s just the plugin, then that’s no big deal, but if it’s something wrong with the html or something else, I would like to know so I can fix it.
