// define('OSC_MEMORY_LIMIT', '64');
to


// PHP memory limit (ideally should be more than 128MB+)
define('OSC_MEMORY_LIMIT', '256M');


Now the website is back to work normally. 

Thanks for feedback

The same problem happened again yesterday (31/12/2022). I haven't been able to fix it until now.

Today fix by
1. Go to Direct Admin to backup database
2. Create a new database, new user, new password.
3. Restore the old database to the new Database but it doesn't work.( error don't pass )
4. Open phpmyAdmin and restore the old database to the new Database, Pass 
5. Go to the config.php file to point to the new Database.

Try posting on the web page. It's back to normal again.

Seems like problems with database, maybe you must restart it when it went down?

Previously, I've tried restarting, but it didn't work.

Well it's definitely problem of your hosting/server/db as database goes bye bye and does not come back ever.
