After installing GP premium as add-on it doesn't show in appearance menu

Hi

Please make sure the GeneratePress theme is installed as well https://generatepress.com/forums/topic/appearance-generatepress-not-available/#post-187280

Okay, I installed the generate press theme. I deleted the GP premium and later on I installed the GP premium again. Still I do not see the item in my appearance menu. GenereatePress theme is installed, not active.
Do I have to use that GP theme instead of twenty seventeen I am using now?

Thanks for your help.

Make sure GP theme and GP premium plugin are both activated :)

Yes, GP Premium extends GeneratePress, so GP must be the active theme.

okay, than I have another question.
I only wanted to change the copyright in the footer of my page so that's why I installed GPpremium (I already had bought it for an other site on which it is working - yes an generate press theme)
Right now on a new site, I added custom CSS in: appearance > customizer > extra css
.site-info {display: none}
so there's no copyright to see at this moment.
I would like to have as a personal copyright
"copyright 2017 @willustration-design.nl" with a link.

How can I do that?

p.s. you can see my site on http://www.willylubach.nl (in Dutch)

That site you show is currently not using GP.

To change copyright message in GP, this should help: https://docs.generatepress.com/article/changing-the-copyright-message/

Sofar I've found out myself:
In my hosting editor I found the file: site-info.php

I changed the code:

<div class="site-info">
	<a href="<?php echo esc_url( __( 'https://wordpress.org/', 'twentyseventeen' ) ); ?>"><?php printf( __( 'Proudly powered by %s', 'twentyseventeen' ), 'WordPress' ); ?></a>
</div><!-- .site-info -->

into:

<div class="site-info">
	<a href="<?php echo esc_url( __( 'https://willustration-design.nl/') ); ?>"><?php printf( __( 'Copyright 2017 by %s' ), 'WilluStration Design & Fotografie' ); ?></a>
</div><!-- .site-info -->

On my page it shows the right text, but the link does't work. So obviously I have to change something more in this code.
And I am questioning myself, will it stay with an update?

Not sure what's going on here. Why are you using Twentyseventeen when you already bought GP?

If you use GP then it should be very simple as the link I provided above.

And to answer your question I don't think the way you did it will stay through update as it's the theme's core file.

The reason why I use twenty seventeen is that I love the way it scrolls with pages and pictures on the homepage.
This way I can highlight my two businesses and my graphic packaging designer job on the home page.
For further (personal, educational en work) info you can use the menu if you are interested in hiring me.

I will shut down the standard copyright on the page and leave it that way.

For a next site I have to learn by myself how to programm the scrolling thing on the homepage so I can use GP theme with the GP premium and edit it the way I want it to be :)

Thank you all for your help!

I'm pretty sure GP can handle everything a twenty series themes can do :)

Glad we could help :)
