Your application is creating pages with ownership of nobody in the directories that have permission 777 and you cannot modify permission of pages with ownership of nobody. We change permission on directories with permission of 777 if some spamming scripts or outbound attack scripts get uploaded in those directories as the directories are writable for world and anyone can easily upload bad content in those directories.
We have recently implemented pre.php and mod_security on our servers which wont allow anyone to upload abusive scripts in the directories with 777 permission. You wont face the same problem again in future which you had in past as the recent installation of pre.php and mod_security will take care of banning upload of abusive scripts.
If you come across similar problem in future then please contact our support staff from our helpdesk located at
