Everytime on a new install i get the same error:
Forbidden
You don't have permission to access /cpg131/config.php on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
I tried version 1.3.1. up to the new beta version 1.3.4. All permissions are set like the should be. After some researche I read on this forum to try and change the name of the config.php and try again. This solves the problem but how do i change it to the config tab in the admin section?
cpg1.3.4 is not beta software, you're mixing things up.
Ask your webhost, they seem to disallow you the use of a file named "config.php", which is a silly thing in the first place. If they refuse to help, search the board for a workaround, as this has been asked and answered before.
I have asked my provider why the config.php is not working on their server. They say that there's no restriction for use of a file called config.php. They blame it on a scripterror!
Can anyone tell me how i could change the config tab to point to the new config file?
Sorry, this is not related to the script - it's a problem with your host. I recently posted in a related thread - renaming config.php to something else. You have to go thru every single file and change config.php to something else. If you search you will come across the thread.
