Appache error log upgrade of OJS 3.0

Hello, I have done clean upgrade with very high values in php.ini for max execution time and memory. and as far as I check that apapche error log there are not specil errors except warnings. IPlease check pastebin and confirm

It also identifies a typo in

Well, I guess that upgrade was successful since apache error log does not contain any special error messages. Right?
