wpForo uses PO and MO files to manage translations. wpForo includes a language file (wpforo.pot file) which contains all of the English text. You can find this language file inside the plugin folder in wpforo/wpf-languages/ directory. The wpforo.pot file can be imported into PoEdit to translate.

Thank you though.

Are there any xmls to start with?

Anyway, i just translated the english phrases into my language so that i have the forum content translated.. seems like a bad approach, but hey.. it works for me

Please navigate to the Dashboard > Forums >Settings > General admin page, find the "XML Based Language" click on "Add New" button to add the new language in the select box.

More info here: https://wpforo.com/docs/root/wpforo-settings/general-settings/#xml-language

To insert French translation and keep the English one, I had to change the second line of the XML to:

<language name="MASTER" language="Français" encoding="UTF-8" version="1.0.0" code="fr">

Now you've deleted the default english phrases so wpForo has no other options and displays Spanshish language. This is not correct.

No, I did not delete the default English phrases; I deleted the Spanish language and all the Spanish phrases, (In my case, langid 2). English is langid 1.

After modifying the database with phpMyAdmin, all I had available was the default English. Then, I followed the procedure to add Spanish again through the wpForo dashboard. Everything worked correctly, and I could change back to English at any time.

after uploading new language you should navigate to Dashboard > Forums > Dashboard admin page and click on button.

I tried that button. I also tried clearing all the caches. It didn't help. The only way to update previously added phrases was to delete the Spanish translation and re-upload, and the only way to achieve that was to modify the database. I posted the steps here in case anyone else is having the same issue.

The XML functionality is extremely useful, but there are some simple changes needed. Uploading an updated XML file for a language that has already been added should update all phrases, not just add new phrases.

Also please note, after uploading new language you should navigate to Dashboard > Forums > Dashboard admin page and click on button.

I translated half of the phrases, added the XML, verified everything was working properly, and then translated the other half of the phrases. When I re-uploaded the XML file, I was surprised to see that wpForo did not update my phrases. It seems a very straightforward update operation. Worse, there is not even the option to entirely delete the language and start over.

I eventually did find a solution using PHPMyAdmin:

• I took note of the langid for the Spanish language in the wp_wpforo_languages table, then deleted that row.
• I subsequently deleted all rows with that langid in the wp_wpforo_phrases table.
• Finally, I again uploaded the XML file through the wpForo dashboard. 

Worked like a charm! All my phrases are now correctly translated.

Again, this process should be automated. I appreciate the ability to translate phrases through the admin interface, but I prefer to have all translated phrases in an XML file, easily transferable to a new forum install.

Thanks

1. You should collect all missing phrases and update XML before importing (optional)

2. Phrase values should not be empty ('key' => 'value'). All should be translated or just left with English phrase.

3. Phrase keys should not be changed, you should only translate values ('key' => 'value')

But we work to create automatic XML updater and eliminate issues related #2 before adding XML info in doc.
