Xenforo xenforo installation error..

It's a new server, new installation of centminmod by:

Code (Text):

yum -y update; curl -O https://centminmod.com/betainstaller81.sh && chmod 0700 betainstaller81.sh && bash betainstaller81.sh

---

Then I installed the latest version of Xenforo.

The new database is ready.

But when I tried to install the xenforo I see the following:

Code:

I have experience in installation centminmod/xenforo, this is the first time I've seen an error.
