Hello, i get a lot of warnings with AKI theme. Heres the warnings:

Warning: count(): Parameter must be an array or an object that implements Countable in /home/lishop/domains/liolishop.lt/public_html/wp-includes/post-template.php on line 284 (I get this above the main header)

Warning: count(): Parameter must be an array or an object that implements Countable in /home/lishop/domains/liolishop.lt/public_html/wp-includes/media.php on line 1206 (I get this above all products)

Warning: sizeof(): Parameter must be an array or an object that implements Countable in /home/lishop/domains/liolishop.lt/public_html/wp-content/themes/aki/woocommerce/single-product/tabs/tabs.php on line 35 (I get this below the product in the product page)

 I also include attachments with the warnings in the page.

If I switch to other theme  the errors disappear.

How can I solve this problem?

I am very happy to announce that I managed to solve this problem my self. I changed PHP version from 7.2 to 7.1
