I have created new language files for Finnish to server. Everything else works perfectly except start date and time selection in Calls and Meetings modules. Calendar doesn’t open from the icon and there are no fields for hours and minutes like in English version. Attached screenshot from Spanish language version.
Have you performed a Quick Repair & Rebuild? What are the versions of your server/php/mysql? It may also be related to permissions, so if you can detail your setup/versions we can suggest recommended permissions to set.
