This article contains information about installing a different software from Fantastico or Softaculous in the root directory.
When using Fantastico or Softaculous, you cannot install more than one script in the root directory. If you remove the script from the root directory and still have problems try the following:
1. In file manager under the public_html folder under the fantastico_data folder click on the file name installed_in_root.php click on that name and click edit file from the cpanel menu on the top (or top right).
2. Change the value of $installed_in_root["kurtscamera.com"] = 1; to
$installed_in_root["kurtscamera.com"] = 0;
That will tell fantastico or Softaculous there is nothing installed in the root folder.
