Suddenly, my system stop working. All error coming out in the error log file. But this time, the error log file had a diffrent formatting. I wonder why.
After checking on the log file, I found out that there are several PHP function not working. The log file show obsolete function. I wonder why.
After 10 minutes thinking, I got the idea that the server made self-upgrade from PHP version 5.X to 7.X . Version 7.X has a lot of new function that makes previous function not able to work.
To solve this problem is to change back the PHP version from vesion 7 to version 5 in the CPANEL configuration.
Now the problem solved.
