Hi Luna,
Development and Production values should be different, that's precisely why PHP includes two templates:
- php.ini-development
- php.ini-production
You need to set up your production server as a production server.
Anyway, given the "until today" part, you also need to check and see what did you, or any other admin, changed, either in the server (software/hardware), the configuration files or within Moodle. There's always a reason from "sudden" problems.
Enable Debugging and also check the web server error log.
