Additional PHP versions not working

Hi all, for reference my system is running Debian 6 (yes its old and needs an upgrade) and ISPConfig 3.1
I have follwed this guide https://www.howtoforge.com/how-to-u...-and-fastcgi-with-ispconfig-3-ubuntu-12.10-p2 however I used php 3.6.31.
The install appeared to have worked with no errors, however it doesnt work, I have the following error in my apache2 error logs.
/opt/phpfcgi-5.6.31/bin/php-cgi: no such file or directory.

Thanks
Martin

 

What is the output of

Code:

ls -la /opt/phpfcgi-5.6.31/bin/php-cgi

 

Thanks for your reply, but it was user error.....

 

Then you should check where the php really got installed because the path you posted is wrong.
