Whmcs decoded version V7.8.0

No permission to download
I am getting error on init.php

Detected attempt to include init.php for a second time. Unable to continue
 
Hello, can you tell me which php version should I use?

I am using php5.6 and I am getting the same error
yes ,this version have more bug not to fix ,you can compare untouched version
 
7.8 was sufficient I think I miss the UI, 8.x makes it hard to work with it
