Madhouse - The templates for the weather is now installed with the weather_install.php script as it's kinda pointless for someone to install those templates if they're not using the weather. If you upgraded from 1.0 and didn't want to run the weather installer again I can attach just the templates here for you.
Preech - The path is your problem. It should be set to the path to your forums, not the url. If you're not sure what the path is, you can create a file with just this content:
PHP Code:
<?php phpinfo(32); ?>
Save it as info.php and upload it into your forums folder.
Then go to that file in your browser and you will see a list of options that were set by your host. One of them is called:
_SERVER["PATH_TRANSLATED"]
Copy that path, paste it over what you currently have and it should work fine.
