Sorry this is posted here, but as you will see, I am unable to post a new question over at the sites meta.
I tried to post a new question on Meta. It all went fine until trying to add a tag. There were two tag buttons, “Proposal” and “Idea”. Clicking either did nothing. I tried clicking in the box so I could type a tag manually, but clicking there didn’t put a cursor there, and typing didn’t cause anything to show. After trying various things, I somehow ended up with a blue bar across the top of the Tags edit box. Sorry, I don’t remember exactly what action caused that.
I also tried posting a regular question on Meta, as opposed to proposing a site. Same problem. Since I can’t add a tag, I can’t post, and therefore can’t report the bug on Meta.
Here is a screen shot showing the blue bar after various failed attempts to add a tag:
