Hubzilla Server PHP Errors: Request for Suggestions

[joemo]

I am trying to install Hubzilla Server on my account and it's spitting out three critical errors (exec disabled, shell_exec disabled, and could not find a command) that I can't get past.

Now, before you reply, I understand why you would not want shell_exec and exec enabled.  I am not a PHP programmer by any means, but I understand the potential security concern here.

 

So, now, my question:

Hubzilla is pretty feature rich and decentralized.  The decentralized aspect is what I was looking for.  Is there another decentralized social network, even one not offered through the Softaculous easy installer, that would not require shell_exec and exec enabled?
