In activity feed or media tab, when I click to open an image, the lightbox opens a WP page saying: “nothing found, try to search with a different tag”. Anyones know what’s happening?

If the issue still persists then kindly provide the debug info log on your website. You can find it under rtMedia Settings -> Supports tab.
