Same issue. I do not want to chmod 777 because it is a big security risk.

I figured it out.
My host was blocking some of the images in wp-admin directory which caused google gears to stop working, too. A 403 forbidden would be returned when the images were accessed. It was only 2 that I know of: toggle-arrow.gif and toggle-arrow-rtl.gif.
Once they added the domain to their whitelist, everything worked fine.

I’ve had 2 blogs give me 404 errors. One of them,
https://blog.mysecurepc.com/
I deleted the htaccess in the blog’s root dir then recreated permalinks by clicking on update permalinks in admin panel.
The other blog still has the 404 problem (same versions 2.0.3). Deleting/creating htaccess did not fix it.

I had the same problem with GoDaddy and 1and1. Each was solved differently.
GoDaddy:
When a subdomain is created a folder of the same name is created off the root dir. In WP under Options I named the WP address and Blog address the same:
https://subdomain.domain.com

1and1:
When a subdomain is created, no folder is created; it excepts everything to be installed in the root. I had to create a destination folder called subdomain (in the admin istrator on 1and1). I named
WP address: https://www.domain.com/subdomain
Blog address: https://subdomain.domain.com

That did it! Thanks.
