I've tried in every way I can imagine to translate the comment_form.php-file.

* I've used poedit and it works for the rest of the site, but not comment_form.php
* I've created a child theme and uploaded the translated comment_form.php but noting happens.

The only way I make it work is if I translate it in the parent theme, but then I'll have to redo it with every update and I would be really happy if I that could be avoided!

Anyone knows how to do it?

url pointing to the issue?

looks like that never made it into the po file. you will need to edit montezuma/includes/template-tags.php line 8

	printf( _n( 'One comment on “%2$s”', '%1$s more thoughts on “%2$s”', get_comments_number(), 'montezuma' ),

Yes, but if I translate it and upload to my child theme the changes doesn't override the montezuma theme like they should. Any idea of how I can change it without changing in the parent theme?

For now you will have to edit the actual theme file. I've sent a note to the developer asking that this get added to the PO file for the next release.

I discovered an error. You should be able to put your translated comment(s) titles at mto->Comments->Comments Titles, but there was some missing code that ended up ignoring these titles. To fix this,

edit '/includes/template_tags.php' and change line 8 (version 1.1.9) from

	printf( _n( 'One comment on “%2$s”', '%1$s more thoughts on “%2$s”', get_comments_number(), 'montezuma' ),

to

	global $montezuma, $comment;

	printf( _n( $montezuma['comments_title_single'] , $montezuma['comments_title_plural'], get_comments_number(), 'montezuma' ),

and change your titles at mto->Comments->Comments Titles and test it and let me know how it works for you.

If it works I'll write up a patch for the next release.
