Your ROOT_URL in app.ini is http://git.osmesh.ru/ but you are visiting https://git.osmesh.ru/MOS/OpenBoard/blame/commit/89709f47dc26505b074fe62b0405d33ebd10414e/resources/library/interactivities/Balance.wgt/i18n/Messages_fr.properties
You should set ROOT_URL correctly, otherwise the web may not work correctly.
