@ravi Shakya – I’m trying to make polish translation, so in poedit I made po and mo files, I name it as: wp-advance-comment-pl_PL and place them in wp-content/languages/plugins/ and nothing happens.
I also tried to translate plug-in manually (as I have it done before update) but I can’t even change encoding of comment-form.php to UTF-8 (ajax functions stop to work).
