Its frontend is developed in Angular JS and Backend in PHP. Yesterday I By mistake made some changes in File but later I forgot that in which file I made changes. But I did not made the changes in controller and database. There is an Admin in this web app and others are users. When users will submit their records in their dashboard by loggin into that and if they make any changes in those records anytime, then admin gets notification with proper timestamp on their dashboard. Admin can send any alerts to any users and in their notification panel user can reply to admin. Both can chat with each other. That module is working perfectly, only criminal images disappeared from that panel. You need to enable criminal image in chat panel about whom admin and users are chating. In create new pending trial cases all the data should be fetched from View Criminal Records because all the fields are taken from Create new criminal info only field is not taken from that. Date ticker to be added in date field. Same form of create new criminal records to be added in three places.
