Steps to reproduce:

1. Go to Content > Web Content
2. Try to add Web Content
3. Assert web content title and content form fields are not editable
4. Try to add Blogs entry or any other content from "Content & Data"
5. Click +

Actual Result:
The new title is gray and can not add Content. It first appears that adding content is possible, because while the fields are greyed out, the IE User can input into the fields. But after clicking Save/Publish, a Success Message displays and no content is actually created.

Expected Result:
Fields are not greyed out, and User can add content.

Note: This issue also displays in "Web content", "DDL" and other Content on IE.
