Fatal error: Uncaught Error: Call to undefined function mysql_real_escape_string

Hi there

I tried to reach the WooCommerce dashboard/reports/clients from adminpage wordpress. Can’t even access it’s settings. All I see is this:

Fatal error: Uncaught Error: Call to undefined function mysql_real_escape_string() in /home/httpd/vhosts/rasputin.ch/shop/wp-content/themes/mystile/functions/admin-interface.php:111 Stack trace:

If I click on WooCommere Orders and Coupons the page will work perfectly!

WooCommerce: v4.0.1
WordPress: v5.4
PHP: v7.2.29

Here is a snippet of the line 111 from admin-interface.php
check this

When running define( ‘WP_DEBUG’, true ) on my wp-config.php file, this is the result:

Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; WooThemes_Shortcode_Generator has a deprecated constructor in /home/httpd/vhosts/rasputin.ch/shop/wp-content/themes/mystile/functions/admin-shortcode-generator.php on line 33
