I can't see the status lamp of Yostseo plug-in. Do you know why?

Hi muktipolice,
If the section from your screen is from posts or pages, then Yoast seo should be display, just make sure that it is enabled -> https://i.imgur.com/zhwaYnf.png also in some cases it may be from a plugin that is interfering, so, in case that you have the seo options enabled and the “status lamp” is not displayed for posts and pages, make a test using only tagDiv plugins and Yoast plugin.
I hope this will help you.
