Font family problem

I bet Elementor is setting the font style explicitly. Have you checked that?

Or do view source see if Arial is being set on the elementor widgets.

Thanks, Yes the problem was the Elementor setting font style & did not read from the template.

@vahid671 go to Dashboard > Elementor > Settings and remove the Elementor default color and font. Check it fixes the issue or not.
