Your ROOT_URL in app.ini is http://git.osmesh.ru/ but you are visiting http://91.221.70.94:3000/MOS/OpenBoard/src/commit/d6762e92fc470323c6d3725da2dd0187ca72bac9/resources/library/interactive/Graphme.wgt/__MACOSX/JavaScript/._AffichageXPM.js
You should set ROOT_URL correctly, otherwise the web may not work correctly.
