how to make the slogan appear

Hello

How to make the slogan appear. I wrote it in the parameters but it does not appear

You can use this custom CSS:

.logo-image small {display: block !important;}

Hi
I couldn't find user.css in the source code?
or a place in the template?

You can put it into file: ROOT/templates/ja_megastore/css/custom.css (Create this file if it doesn't exist now)
