I have only one folder left in my site called "cache" which has no files in it. I have tried to delete it using the filebrowser and FTP but it won't delete. I also tried it after changing file attributes from 755, 777 & 000 and it won't delete.
I need to delete it to use the "one Click Phpbb" install as I have tried but it won't install while that directory exists.
I don't want to delete the site (domain) and start again because it has a large Mysql database on it and if I delete the domain I will delete the db I guess.
