[deleted] In your extension list for hashtags it says version 3.0 right? And it is activated? You can try also clearing your browser cache, and from your dashboard in that tools menu select clear cache from there as well. You might also try editing one of the posts where the hashtag is not working and re-posting it. Sometimes that helps things update.
If none of that works, then do you have errors in the browser’s dev console? What browser and browser version are you using?
