Please make sure that mysqli PHP extension is installed on your server.

Thanks.

Here’s the content of error_log under /var/log/httpd directory. At first i thought it was related to Selinux so i turned it off and reboot Centos, but seems like it still didn’t work.

Could you please take a look at it and tell me what happend?

You should check your error log files for more information about this.

Yes, i extracted the minibb package at /var/www/html. You can take a look again at the process i did on the last post.

Did you install MiniBB in the document root directory of your server?

If the directory ‘vhosts.d’ doesn’t exist, create it with:
mkdir -p /etc/httpd/vhosts.d/

It didn’t work. Here’s the output when using that command.
tee: /etc/httpd/vhosts.d/mydomain.conf: No such file or directory

shell returned 1

Press ENTER or type command to continue

So i think it could be something wrong with the vhosts.conf or something because even root user couldn’t do that,
