Installing Drupal

Anyone know?

Have a running 8.0.0 rc2 site running under domain A. When I simply rename the site's file directory such that it responds at domain B I get the following:

Parse error: syntax error, unexpected 'class' (T_CLASS), expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$' in /example/core/lib/Drupal/Core/Controller/ControllerResolver.php on line 151

I got the following exception:

Dear Users!

I need some help for repair this error message - "Forbidden

You don't have permission to access /node/ on this server.

Apache/2.2.22 (Debian) Server at phoenix_art.webmuvek.hu Port 80"

It showed when you try to click at the bottom of my page on 1 2 3 . . . pages link.

How could I solve this?

Everything I did before it broke changing the drupal theme to another one.

Thanks!

I am trying to migrate a drupal based system i have been running through a server set up on my own
machine. I originally set up drupal 6 from the pack offered by heart internet, the hosting provider, but I am currently on drupal 7.41. I deleted the
files and created a new database. I unpacked the files locally and uploaded through ftp using
dreamweaver. The install ran successfully with no errors. I have been adding modules and received an
error message regarding HTTP access. "HTTP request status Fails
Your system or network configuration does not allow Drupal to access web pages"

I posted previously about problems associated with my attempt to install drupal commons on an Amazon cloud server.

The installation failed because of two issues: 1) needed to increase PHP Max Execution Time to 120 and 2) OpCache is installed but is not enough space to successfully install Drupal Commons. Change the capacity to at least 96.
