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/2000d94ee1bc2507f900c2a44d071f60ba4e18c3/resources/library/interactivities/Tableur.wgt/js/help_fr-template.js
You should set ROOT_URL correctly, otherwise the web may not work correctly.
