How to remove metadata?

Hello @ildomandatore

You can use the following code in additional CSS box:

.single .entry-meta {
display: none;
}

Thanks ??

Not if this was the CSS I entered, but it has created 404 errors in the past.

Hello @ildomandatore

CSS doesn’t create any 404. make be you have customized some code of theme or plugin or URL of your website that will create error on your website.

Thanks
