Having moved my blog to a subdirectory and while doing so updating it to WP 2.3.3 i now have an 500 internal server error page on eith post-new page-new or edit post.
The post-new page gives a straight 500 error with nothing else but the other two show the page then have the 500 error in the post box.
My server log shows the following error: Premature end of script headers: /usr/home/phonebar/public_html/blog/wp-includes/js/tinymce/blank.htm
Can anyone offer advice on the problem and how to correct it??
