The issue is in SSL without redirect
If you will open link as you sent me it will be working – https://bepkhanhtrang.vn/brands/hafele
If you will open common link it will not – https://bepkhanhtrang.vn/brands/hafele
If your site is configured to use SSL there should be always SSL. I mean https with S at the end.
Configure redirect from any non SSL page to https.
As for the price filter – this is WooCommerce issue. You can btw tell them about this. We already message them same as few our clients.
The issue is next – database fields for the prices in their own tables are set as decimal(10,2). It means 2 numbers after the “,” and total 10. So before “,” we have 8 numbers only. 100000000 need 9 numbers before “,”. Any prices above 99999999 will have this issue in any filter, even WooCommerce’ filters have this issue as everybody are using the same tables provided by WooCommerce.
We cannot fix this as this is WooCommerce tables and they should do it.
