Took backup of files, deleted the unwanted plug-ins on the backend and tried updating the WP using: http://www.simsy.in/wp-admin/update-core.php?action=do-core-reinstall
But, nothing happens after the following message:
Update WordPress
Downloading update from https://downloads.wordpress.org/release/wordpress-4.4-no-content.zip…
Unpacking the update…
Verifying the unpacked files…
Is there a safest or other way to do the update and see if the website content, theme and plugins gets restored?
