Modules appear to be installed, but aren't there

I see the modules that I've installed, all from the base package, fresh install of 7.0.3, but all of them go to a 404.  The admin url is in the format:

http://mydomain/m/facebook_connect/administration/

Same issue with the Files module, going to /m/files/administration

I suspect this is a setup issue, permissions or something like that, but I followed the simple install, the messages came back saying it was installed, I'm not sure what to do now.

Suggestions?

3 possible problems.

1) .htaccess file from dolphin zip file was not uploaded to server. (this is a hidden file on some computers. Show all files to see it)

2) mod_rewrite not enabled on server. Contact host for this problem.

3) apache server not setup to process the .htaccess file. Again, contact host for this problem.

Yep, .htaccess was the problem.  My solution was to explicitly allow it in the dolphin configuration:

Thanks!
