How to fix "No input file specified" error
This error is usually produced by incorrect directives in either the php.ini or the .user.ini files for your website.
To resolve the problem check if there are files named php.ini or .user.ini in the document root folder of your website, open them and delete the following line:
open_basedir=/some/invalid/path/here
You can use the Site Tools -> File Manager to access and modify the files.
