thank you very much or your answer. I reset the fonts to default and it works now!

I still didn’t get an answer about the RTL:
1. product page is not RTL – the image is on the right side and the content on the left.
my website language is Hebrew so the settings are correct.

and about my last question:
in the shop page, in the product category widget, the hierarchy is not as in the category setting page. I want to have the father category first, then subcategory and then the sub-sub category as they configured in the category setting order (the widget is set to follow the order of the categories)

thank you very much!
