Hello! I have the same problem…
I’ve been testing everything you say. But it does not work for me, now almost everything is in English!!!! First I downloaded the .po from https://translate.ww.wp.xz.cn/projects/wp-plugins/the-events-calendar/stable/es/default and then I replaced it in wp-content/plugins/the-events-calendar/lang because I could not find “% 1s for% 2s [month view]” using Poedit. But it still did not work.
Then I read all your dialogue and I downloaded the .mo. Now I changed the two files in / wp-content / languages / plugins . And now it’s worse! It’s almost everything in English. I think I’ve already changed so many things that I do not know what I’m doing wrong … Help please!!!!
