The post to the blog is sucessful, but the code is inserted as if it was in the WYSIWYG editor, even though that option is not on for the posting account. I have also tried removeing all of the markup plugins, but unfortunately that didn't help either.
An example of what happens is that this:
becomes<div style="float: right; margin-left: 10px; margin-bottom: 10px;">
Can anyone point me in the right direction to resolve this? Many thanks.<div style="float: right; margin-left: 10px; margin-bottom: 10px;">
