I just updated to WP 3.8 and it seems like there is an issue with posts. If i try to edit any of my existing posts I cant see the text itself, it is there but it seems like it's white coloured font on white background. The same thing happens when I try to write a new one. Also I can't switch between Text and Visual modes of writing and my old posts are in 'text' mode meaning when I select the text I can see all of the HTML code but the posts still looks ok on the website.
