Today I get the answer.
My coder updated the theme for you and he fixed the problem.
You did some changes in the main theme and you should take the backup. We will not able to know that you had the changes. Because we do not support the customized/changed site, as the rule. The main theme is always updated. You should do the customization in the Child theme, it is safe for your site, it will not change the default and all will not be lost when the Main theme is updated.
Even when you ask the support, you need to inform us about the changes. So we will pay attention.
