Hello,
1) Issue with the font on your site is not related to our theme but to your server settings and http/https http://prntscr.com/vpfpb7
2) Enable Elementor builder for the Static Blocks https://www.8theme.com/documentation/xstore/support/static-blocks/ and edit the footer static block according to your needs using Elementor builder.
3) You need to translate theme and XStore core plugin. Read the documentation https://www.8theme.com/documentation/xstore/theme-translation/base-theme-translation/
If you still have the issues with the translation of the theme and core plugin just reply back and provide us with temporary WP Dashboard access to your site and screenshots of the missing translations. We’ll do our best to help you.
Regards
