Ah, it looks like some of the settings in the legacy widgets are missing.
Have you tried using the Latest Reviews block in your sidebar instead of the legacy widget?
If you cannot see the block editor on the Widgets page, you can enable the Widget Block Editor that was introduced in WordPress 5.8 with a code snippet like this:
add_filter('use_widgets_block_editor', '__return_true', 100);If you do not wish to use the new Widget Block Editor, you may need to use the shortcodes in a text widget instead (until a fix is released for the legacy widgets). For example:
[site_reviews display="10"]
I’ve enabled the widget block editor with your code snippet, done my setting, from 10 to max 7 reviews, and disabled it afterwards (don’t like the block editor at all). Now it looks like that: Block: 1 Block HTML: <!– wp:site-reviews/reviews {“assigned_to”:”custom”,”category”:”custom”,”display”:7,”rating”:1,”user”:”custom”} /–> Works fine for me. Thanks a lot for your prompt support.
