I have just upgraded from 2.86 to 2.9 and now when I edit of post a new post I get a white or blank screen from post.php and "done" in the bottom of the browser window.
I have seen other people pose this but without any answers and those threads have been closed.
The curious thing is the articles post ok to the blog, and this only happens in admin ???
its frustrating more than anything else - any thoughts please
The blog I need help with is rapidbi.wordpress.com.
