[Help-SOLVED] Transferring a GS Website to A new Host - No Design?

[TDT-Alpha]

Seems that I forgot that there's a "Website URL" in the settings, changed that.
Ohh... Forgot that on other servers than mine there's "File Permissions" XD Fixed that, too.
And it's not working, after changed almost the whole website to CHMOD 777 it still says:

Error: Unable to continue: Unable to write config file. CHMOD 777 the folders /data, /backups and their sub-folders and retry

And won't change the base URL...

EDIT:
It WAS changed, and it's working but still says the above error every time I change something XD
