There seems to be an issue with the Search string not being translated on the normal search. I’m using WPML to translate everything and it doesn’t seem to register at all. as you can see here: http://sotahistoriamatkat.fi/matkat/
Thanks for your post. Some of our translations are a bit outdated which could account for the missing string (and others). If you tell me which language files you are using I can confirm that. Updating the translation is probably the best thing you can do here 🙂
Our plugin does not currently work properly with WPML, so there could also be issues associated with that. We are working on making it compatible in a future release.
