Hi,
It seems that the font is not being loaded because of the https protocol.
It’s advised to use the HTTPS plugin

Regarding the portfolio you should try to deactivate all plugins except SwiftFramework and Woocommerce.
If you have any modifications in the child theme you should also active the parent theme to discard any situation caused by the child theme.
