Hi.
Thank you for contacting us.
1. We have fixed that issue on your site.
2. For the theme options issue, we will check and update it to our theme soon.
3. For the portfolio permalink, because you have the page https://superplus.com.co/portfolio1fdfd/ with the portfolio shortcode.
For the https://superplus.com.co/portfolio/ page, this is a portfolio archive page, that layout will different from portfolio shortcode.
4. For the shop page, you can add a top or bottom content to the shop page. Please go to Theme options/ WooCommerce/ Archive product/ and show the archive page content top or bottom as that config. Then go to shop page and add the content (slider) as you want.
5. For the compare issue, we will check and let you know soon.
Thanks.
