I've inserted an image into the top of a posting. I don't with the text to go on the right but start underneath. In 2.3 I simply added a <BR CLEAR=LEFT> after the image and no problem.
In 2.5 I type this in and publish or save... the page reloads and "clear=left" has been deleted from my changes. I've tried deleting the wordpress tags, and starting over, but same thing; won't allow me to clear the image.
