PHP7.0 FPM + Magento proxy_fcgi:error
I am having the error below in the apache error log when accessing the Magento admin backend (version 1.9.4). The error that is shown on page is: No input file specified.
The frontend of Magento is accessible. My VPS specs are Ubuntu 16.04, PHP7.0, Apache2 and PHP7.0-fpm. I am already struggling with this for 10hours so now I am looking for some help.

All help is highly appreciated.
