This question may be related to a resolved thread.
I see several folks have had this issue. I recently upgraded from 1.6.9 to 1.7.1. The upgrade appeared to be successful, however I received this message on visiting the site:
The system does not appear to be installed. Click here to install it.
When I searched the forums I found that it could be related to perhaps not removing the update.php file (which has been removed), not restoring the config.php files or not having their permissions correctly assigned (which were all fine) or perhaps a problem with the path.php.
Other than backing up the path.php during updates, I’ve never encountered an issue with it or even bothered to look at the file.
So I see the file is completely empty. I see from this thread http://ellislab.com/forums/viewthread/168543/ and a couple of others that the issue could be path.php.
So I uploaded an archived path.php with the correct system path.
Now my site is finally displayed, but none of the design is displayed. None of my archived path.php files have any of the following information included:
$template_group = “”;
$template = “”;
$site_url = “”;
$site_index = “”;
I went ahead and added the template_group but that doesn’t have any affect.
