Hi friends,
just messed the websites at host by changing permission settings :( none of sites are working now!!! it gives
Forbidden
You don't have permission to access / on this server.
error! how can i fix it?! should i make files' permissions as 644?
thanks!!!
I think that 755 should do.
Basically, you shouldn't grant write permissions for any file/directory to anybody but yourself (the owner), except for dirs/files which are explicitly required by a particular website/framework to be writable. A common example would be a directory for uploading avatars by users of a forum application.
What matters is that you most probably need the 5 for others (hence, you might try 705 and it still could work) to grant execute access for foreign users. While it might not make sense to set +x for all your website's files, the directories use the execute right to check whether the user is allowed to enter that directory. If you set the rights of everything (including directories) to 644/744, nobody except the owner will be able to browse the directory structure of particular folders. As the http daemon hardly ever is run as the directory owner's process, it might be the reason why your website stopped working.
