Regards from spain

what´s docs must uploaded to media folder?¿?

Just try at 777 and put it later on to a safer security setting until it doesn't work and go back one less strict.
It has something to do with multi hosting and ownership. Joomla! runs best onder apache rights, but most hosters do not know how to set the security properly so they have run joomla! on your 'account'.
This is done to prevent from one domain able to affect a lot others. If it only works under 777 you should contact your hoster as the settings are not right and unsafe for normal running a site.
