Any ideas to fix the issue?

Hi @D941x99 -

That’s a really really old version of NC. Is this an existing installation that just hasn’t been upgraded in a LONG time or is that a new installation you’re attempting?

Anyhow…

This path doesn’t exist or is unreadable or unwritable for some reason. It’s where PHP in your environment is (apparently) set up to keep session data (which is critical).

I’m not familiar with the UCS stuff, other than having run across it mentioned a few times. Doesn’t it have its own support channel or something? I ask because my understand is it’s turnkey environment or something. Some of the conventional solutions might not be appropriate for it.
