Authoring is not supported in IE 11.
Images may be viewable in authoring but not in the regular published view of the page. This happens because the image size is not defined. It was most likely to occur previously in the Image Cycle but now may be an issue with images inside table cells. The remedy.
If a page was moved from one site to another (such as from the main subsite to a child site) prior to the upgrade (11/1/13), the links on that page may be broken. The remedy.
XML Readers on pages that were moved into a child site may not contain the correct URL. Remedy: Adding the child site to the URL data fixes the issue.
