I’m on vacation at work but still with the website of the NGO. Now I’m focused on the part of the blog and bbpress. Attached some screenshots to see if you can help. It turns out that some strings are not translated. Languages create the folder and copy files WordPress installer original translation in Spanish of and appears correctly if you open Poedit but the labels in your template-tags.php who remarked in capturing are not translated. I thought it was because they were using _e () but researched and functions is double underscore __ () as you did.
So to confirm, you’ve opened the ultra.pot file in Poedit and added those strings to your es_ES translation? Is that correct? The strings you haven’t yet translated should be in the ultra.pot file. For example, 2 comments in your screenshot is:
Thanks for your reply. The problem is half solved. Your strings are translated now after I added the translations in your ultra.pot but in comments area the sentence like “2 Comments” didn’t translate. I open WordPress files in Poedit and the strings of this texts have translation. I confused. Do you know what’s happening?
