I18N Issue

This plugin slug is famethemes-demo-importer, but the current Text Domain is demo-contents. Change the current Text Domain so it is equal to your slug and modify the text domain in all your source files. This change is needed because your “Requires at least” is below 4.6. (see https://developer.www.ads-software.com/plugins/internationalization/how-to-internationalize-your-plugin/#text-domains)

“Requires at least” (4.5) is below 4.6 so a load_plugin_textdomain is needed, please make sure you load it at a certain point in your plugin. (see https://developer.www.ads-software.com/plugins/internationalization/how-to-internationalize-your-plugin/#loading-text-domain)
