Theme error

Hi

Have error with the team I bought from you.
Not sure if it's a theme installation error or demo error.

1. Logo Show on subpages but not on the frontpage.

2. The single product page are wrong. Everything are displaying vertical. The price, add to cart button and so on should display to the right.
I have tried all of the options in the theme menu, without any luck.

Here you can also see some widget errors.

3. When edeting the frontpage from admin, everything are really slow. When clicking on a box in the page builder, the box take really long time to open. It's only loading.....

4. Error checkout. after adding a product and click the checkout button. The checkout page are not there.

5. After adding a product from admin. Several times all the information/text and are gone after I click update/save.

6. After updating, the theme/site do not stop "loading"

7. Widget error: Warning: Invalid argument supplied for foreach() in /home1/europe1/etsy24.com/wp-content/plugins/kuteshop-toolkit/includes/widgets/widget-product-filter.php on line 31

8. The popup window "shopping cart" cannot be used in chrome or windows browser. It disappear before you are able to click any buttons.

The site are hosted with Hostgator. I have several wordpress sites here without any issues, so I don't think it's anything with the hosting

Thanks
