This is not a problem in cms, but on your server.

Here is exactly what you need https://stackoverflow.com/questions/21038682/403-forbidden-error-on-wamp-server

yes my server was indeed the problem as it wouldnt let any one into my  site untill i went to a dev site im familar at and ask for help. My problem was solved by changing one file (so far as i know)

the file was the httpd-vhosts.conf which at default has this in it:
# Virtual Hosts
#
<VirtualHost *:80>
  ServerName localhost
  ServerAlias localhost
  DocumentRoot "${INSTALL_DIR}/www"
  <Directory "${INSTALL_DIR}/www/">
    Options +Indexes +Includes +FollowSymLinks +MultiViews
    AllowOverride All
    Require local
  </Directory>
</VirtualHost>
i was in structed to change it to:

# Virtual Hosts
#
<VirtualHost *:80>
  ServerName localhost
  ServerAlias localhost
  DocumentRoot "${INSTALL_DIR}/www"
  <Directory "${INSTALL_DIR}/www/">
    Options +Indexes +Includes +FollowSymLinks +MultiViews
    AllowOverride All
  #ace  Require local
  Require all granted
  </Directory>
</VirtualHost>

that stuff is confuzing as heck  .
i may have edit the add_vhost.php path too
