I updated my site to WordPress 2.5 expecting to find some kind of text widget, but don't see one in the default interface. So I download a few plugins, activate them, and they show up under "Show all widgets" but clicking the link "Add" merely changes that word to a link named "Edit" (and clicking the link "Edit" does NOTHING).
This is the behavior on Firefox. Attempting this on IE causes it to crash every time. Safari runs as Firefox does.
Finally my roommate selected in the drop-down menu "Show unused widgets" and it revealed that somehow I had added a widget to the current widgets on that screen, and that I had somehow added a widget to the current widgets on that screen. Unfortunately, NEITHER of those widgets managed to yield anything to my published website after I filled in the blanks and clicked save.
The website is http://www.women2.org and I am joining the angry mob. Seriously! Don't release a completely bug-ridden widget interface, because people's websites are now seriously mucked up. Documentation is meager, there are deadlinks or nothing in the codex. Sigh.
