Several months ago I accidentally uploaded the folder containing Drupal 6.25 core files to sites/all/modules.
The site now sees that folder as the base install and ignores the installation in the site root. How can I safely get Drupal to look at the files in the site root as the base install and delete these files? I tried simply deleting them when I did it and it takes down the site with a configuration error.
Configuration error: 500 - Internal server error - neither front end or back end will load
