Theme does not support localization

Here is the 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.

Naming Issue: Author uses unsupported language file naming convention! Instead of example de_DE.po the non theme standard version chun-de_DE.po has been used. If you translate this Theme, only renamed language files will be working!
