Doesn’t remove author

I’m running WordPress 4.9.5, and while the plugin removes the date, it doesn’t remove the author.

So i’m left with, “Posted on by X.” It also doesn’t remove the Category, and for all i know, doesn’t remove the other elements either.

This plugin has a nice idea and is very simple – a big plus – but the author and category hide, possibly along with other fields, doesn’t work.

If it was revised to fix these things, it would also be a great bonus to get rid of the incidental fields as well eg “Posted on,” “by.”
