Your ROOT_URL in app.ini is http://git.osmesh.ru/ but you are visiting http://91.221.70.94:3000/MOS/OpenBoard/blame/commit/123ebf1d957e48227b0819d8236cba57aa52a0d2/resources/library/applications/Wiktionnairy.wgt/script/languages.js
You should set ROOT_URL correctly, otherwise the web may not work correctly.
