Translation readyness

As you can see on https://wp-schulung.ch/suchen/ (you can search for “zügeln” or “hacked” for example” WP Remote Search works but shows some weird letters from the json instead of only the result-url and also it states “We found 4 articles that may help:” and it seems not possible to translate.

no load_plugin_textdomain call and lacking metadata

Any chance rthis gets updated?
