(I have 3 other blogs without this issue)
On my post page the uploading area has lost its formatting and is preceded by CSS, beginning with ".attwrap" and ending with ".#links textarea" (as found in inline-uploading.php) I can scroll down the iframe to find the text links and inputs for normal uploading procedures and the formatting problem disappears after uploading an image. I replaced post.php and inline-uploading.php with fresh copies and no change. Could it have anything to do with:
<?php echo $style; ?>
as that is what precedes ".attwrap" in inline-uploading.php?
