You can still get the account erased if you wanted, however I did jump in and nuke the 3 folders that were leftover from the Wordpress install; if I'm right, it should let you try to install it again now without problems, since the only file left is an error_log.
If you still want it erased, fill in the form below:
Account Deletion Request - Please delete my free hosting account.
cPanel username:
( ) Inserting an X inside the parentheses signifies that I have made all necessary backups of my free hosting account and will not hold x10Hosting responsible for any data I am unable to recover after my free hosting account is deleted. The X also serves as my digital signature verifying that I have proper authorization to request account deletion of the account specified.
If you choose to keep using the account, do nothing and the thread'll close itself - if you can, I'd also recommend trying to download wordpress from their site and manually installing it instead of using fantastico/softalicious - sometimes the "auto installers" don't set it up so it can actually be removed later.
Edit: Oh and for the record too, it looked like the permissions were messed up bad on the folders, and a prepare-removal script that got ran failed because chmod() was passed a file/folder that didn't exist (that's the error left in the error_log). That's prolly why it wouldn't let you remove it.
