Localization gives the following message:
Compatibility: Loading Issue: Author is using load_textdomain instead of load_theme_textdomain or load_child_theme_textdomain function. This may break behavior of WordPress, because some filters and actions won't be executed anymore. Please contact the Author about that.
It is also impossible to translate the theme using Localization.
Added a new language (set in wpconfig and works fine with other themes) scanned the code, entered translations but nothing.
