HOT Cars

Hi, New user here, new to joomla and new to the forum (please be patient it may take me a while to understand any fix to my problem )

I have paid, downloaded and installed hot_cars17_hotstart, but when i go to www.mydomain.co.uk/joomla16/administrator i get the following error

Forbidden

You don't have permission to access /joomla16/installation/index.php on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

I have joomla 1.7 installed into a folder previously named joomla16 and it was working fine as administrator prior to installing hot_cars17

Can anyone shine a light on my flight?

my full site link is

nick.peter-lovegrove.co.uk/joomla16/installation/index.php

Go to your hosting file manager and change folder and files permissions (CHMOD) to 777 (or 755)

Thanks Ivan

I have changed permissions but am now getting

500 Internal Server Error

i get "Not Found".

oops.

And now?
