Hi Vadim. Thanks for the quick report! There was an expected downtime of AMOS UI translation due to the site upgrade. The site is now running latest Moodle 2.2 code and thence AMOS strings now live on the 2.2 branch in the Translator.
Couple of minutes ago, the site updated its strings and AMOS should appear as translated again. Please let me know should you spot any other issues.
Yes, amos is now translated, but i still cannot edit string using translator.
When i edit something and then click outside of translations field it becomes permanently gray and does not updates string. Look like something is wrong wth AJAX
