Hello,

Now the theme has been updated. https://gyazo.com/0dd2174a6ca57115af14b4501fb69c07

The plugins not related to the theme are not activated. When I try to activate the theme they crash the site. So, please make the full backup of you site as it is now without additional plugins, then try to activate your parent theme, if it is successful, then activate the plugins one by one checking the site, to detect what crashes the site.

Best Regards
