500 & 5xx server errors after upgrading to PHP 7
Im using Apache and PHP, then I upgraded from PHP 5.7 or sth to PHP 7.
After that Google Webmaster/Console screen reported the site had lots of 500 server errors.
Then I fixed it with modifying hosts file and httpd.conf, now the console screen didnt show any error.
Webmaster still reporting lots of increasing 5xx errors, and yesterday server was restarted dozen times like the following log file. Then I didn't know how to fix. Then it's ok again though i didnt do anything. But the server errors seem still existed. What should i do now?
