I did wordpress core update from the wp-admin and suddenly the site is 500 for both front end as well as admin section of the website. I tried accessing .htaccess file but its not there at root directory (where wp-content folder is available), I created php.ini file (with memory-64Mb) but its not working.
Below is the server log of the time when I did the core update.
