When I am in the monthly view, the words search and location on top are not transpated to Dutch yet. If I check the .po and .mo files, I can’t find a string to translate for these formfields. This looks a bit messy now.
Thanks for posting. The problem is that the Dutch translation is outdated. If you’re interested in working on it, I’d love to have you update the translations for The Events Calendar and Events Calendar PRO. And in exchange, you can get a free license for Events Calendar PRO (or another plugin of your choice).
