subdomain cannot be opened after firewall activated

[simonlee]

Look closer on permissions in sub folder.

Yes , my ftp permissions is following the old server.

Here is my old server permissions and it could be del or covered
eg:
template 755
-images 755
-- a.jpg 644

But now it can't be del or covered with folder or document under images or below .

Only can do this in template folder

So There must be some problem with the setting .
