I don't have any idea why but when I edit style.css today (didn't happen yesterday) it replaces everything with one long line of question marks (?????) when i save it.
This is really frustrating. I am lucky i could go back and copy my style.css or everything would have been lost!
I've searched but I couldn't find this happening to anyone else.
I've tried overwriting the file via ftp but it still does it!
I remember this happened one other time to me but it resolved itself... it's not going away this time.
