Problem on cache redis?

Dear staff,

when i create a new blog post (article), change author and publish it, on the frontend/homepage of the site remains my nickname, but in the article there is the author name (right!). It is strange because the homepage is not cached so it should display the right name author, otherwise in the article (that is cached) the name is displaied well… how to fix it? I use litespeed server + litespeed plugin and redis cache..
