While installing joomla using fantastico I am gettingg this error please help me The installation can not be completed: - You chose to install in the main directory of the domain diggxchange.info, but there are conflicting filenames, therefore we can not proceed. Following filenames already exist in the main directory of the domain diggxchange.info (path="/home/diggxcha/public_html/").You must manually remove these files before proceeding with auto-installation: images
Use your filemananger to access and delete everything in your public_html folder - at least the images folder and files you don't need. Otherwise, try to instal deeper - public_html/joomla/ - you can always make a redirect to this. At least then you'd know if it was possible to set up. If I were you I would install it manually - it's not hard.
delete the files on your root directory and try it again. i think installing joomla on a sub directory is not a good idea
