Problem/Motivation
The problems below are like related, so I reported together:
1. Top Region non-Clicking: I use zero point theme, the blocks on "top region" is not clickable. Moving these blocks to other region, no problem; moving other blocks to this region is also non-clickable;
2. View Click: for any view, new or existing, when I add Contextual filters, there will be popup window. pick a field, click apply. so far so good. Then to next window to select filter. At this window, no matter what option to pick or even no change, the button "Apply" is non-responsive. There still is a little hand sign, just no response. No clicking issue for button "cancel" or "Remove". If clicking "Cancel", there will be a error message: The submitted value in the Profile type element is not allowed;
3. View Access: In view access, the set-up window doesn't have "for" selection (this block override, all displays, revert to default). They were here before.
Steps to reproduce
I don't know when these problems exactly started. I noticed the view access and Top Region problems a couple of days back, and View Click problem today. I upgraded my core to the latest version a few days back, not sure whether these are core related. I cannot think of any other modules could cause these issues.
I want to emphasize that these problems are across all views, and I have had these views working fine in the past, so it is not view configuration problem.
