Tried to in cpanel filemanager they show deleting then reappear on refresh????
Can you try changing the chmod of the folders to 777?
It seems like you might have a file ownership and permission issue.
Please login through an FTP client and look who it says under the column named OWNER. It should be a bunch of numbers. If its 99 99 (or 0), then it means the files somehow ended up as owned by "nobody", which I've seen happen before. In this case, you probably won't be able to change the chmod permission either. In this case, an admin will need to handle this.
