I'm running 2.8.4 of WordPress. While I have More Fields disabled, everything works fine. When it's enabled however, it removes my ability to add tags to a post in the regular edit screen (Quick Edit works fine, however).
Basically, when it's not normal, there are three things broken. First, if you click on the text box, it's supposed to remove the words "Add new tag" and replace it with the cursor. It doesn't do this, and you have to manually delete the words that are there.
Secondly, when I type the tags in (None of the suggestions pop up in the meantime) and press the Add button, nothing happens. The tags don't get added, and they aren't removed from the text box.
Finally, clicking the "Choose from the most used tags in Post Tags" option moves the screen down, but no options appear like they are supposed to.
I have 3 boxes in the "Manage Boxes" screen. One of them is a 1 field text box. One is a 2 field text box. The third is a checkbox. they are all set to the "Right" Position. The only thing checked in the options tab is "Show type select".
Has anyone seen a similar problem? Everything worked fine until I came to 2.8.4. I've considered deleting the boxes to see if one of them is causing the problem, but I didn't know if deleting a box would alter my previous posts that have used them. Suggestions?
