I deactivated all plugins and used a default theme, the error didn’t change. The method causing the error is in line 151 of /src/Events/Calendar_Embeds/Admin/Singular_Page.php. It needs a WP_Post object as param. You call it from within the same class, passing $this as param – so an instance of the Singular_Page class. I don’t think $this can ever be a WP_Post object in this context. Please ask the team to look into this. Thank you.
Thank you for your reply. I didn’t take any Steps, a long running site just stopped working. The method “add_copy_embed_button” is only called from within the file its defined in, so i don’t see how i can fix it…
Thank you for your time. The translation files are correctly placed, Polylang and all the translations are working as expected. When I load the page, it is completely in German – including the Event Calendar. When I interact with the calendar, it fetches its new HTML via xhr. And that fetched HTML is the English version of the calendar. So Event Calendar uses the right language on initial page load, but falls back to English on xhr.
