Missing serbian flag and language

This looks like a new predefined language request, which should not cause one-star? It still supports any language, you simply enter the information needed on language editing page /wp-admin/options-general.php?page=qtranslate-x&edit=xx
Please, send us all the information as you entered on that page together with file for flag you wish to be in predefined set of languages: https://qtranslatexteam.wordpress.com/contact-us/

Hi John, you are right. sry for 1 start. I will remove rating. How to edit?

Did you send us the information for serbian language? We would love to put it in the list of predefined languages.

To edit the review go to the link https://www.ads-software.com/support/view/plugin-reviews/qtranslate-x#postform, same link as you used to submit it for the first time. WP allows one only review from a person per plugin, so same link now allows you to edit your the only review.
