Contribute cannot verify your connection information... Please notify your administrator."

Question

After a initial network error last night, The Shared Settings
file was zapped. Contribute decided I was no longer the Admin, and
the Editor's connection also disappered.
I found the note that's pasted here, in the Contribute
Forums.
"connect to your server (using 3rd party ftp client) and
delete the _mm folder located on the root of the website - recreate
your connections and that should solve the issue"
I deleted the _mm folder. When I tried creating the
connection anew, contribute said, "Contribute cannot verify your
connection information... home/justandpeacefu/html/. Please notify
your administrator." Now it's the same error every time. I am
unable to make the new _mm folder.
Contribute Tech support sent me an email which didn't help.
It's at the very bottom.
Items 1-4 in the email are not the problem.
I am able to connect to the server, after the tech support
person reset something there.
I can make folders, and pages in FTP application;
there are no special characters;
permissions are fine;
Item 5 did not have any effect. I turned off Apple's personal
firewall, quit contribute, and tried again. Unsuccessful. Same
error.
ANY SUGGESTIONS, ANYONE?
Text from Tech Support:
As we have discussed on the phone earlier today, here are
common causes of getting a "cannot verify connection information"
when creating a connection in Contribute:
1. Not enough permissions on the root of the website - Make
sure you have enough permissions on the root of the website. Using
third party FTP software, verify that you are able to create
folders, upload and rename files, and delete files on the root of
the website.
2. There are special characters on the folder name of the
folder you are trying to connect to - Avoid special characters as
Contribute is not so compatible with them.
3. Incompatible FTP connection settings: When you are asked
to enter your FTP account information in the connection wizard,
click the advanced button. Make sure that the only options selected
are: "Choose FTP Server Settings Manually" and "Use Passive FTP to
connect to the server".
4. Verify that the FTP server is pointing to your web server.
Example: upload any temporary HTML file on the root of your
website; when you visit the URL:
http://[your_server
you should see the page render; You should not get a "Page cannot
be found".
5. Turn off any software firewall / antivirus running on the
background to isolate possibly conflicting processes.

Answer 1

I'm having the same problem as andres in the original post,
the message comes up when trying to Continue out of the "Remote
Path Info" box. I am able to browse to the location so Contribute
does know its there. This is with Contribute 4 on Mac OS X
connecting to a Linux server.
I manually ran the FTP connection tests via command line:
http://store1.adobe.com/cfusion/knowledgebase/index.cfm?id=tn_19496
and all tests passed successfully
I also downloaded and ran FTP Connection Checker (on my
Windows machine) at:
http://store1.adobe.com/cfusion/knowledgebase/index.cfm?id=tn_19012
and passed all tests successfully.
The wording with these tests imply that they are the same
tests run by Contribute, i doubt that to be the case since these
pass but Contribute fails.
I have tried this with the site root and _mm folder set to
permissions of 777 with no luck. I am able to connect and edit
successfully with Dreamweaver and FTP with Transmit (Mac OS X).
I'm about out of things to try and my deadline to train the
client is coming up. Any further insight on this would sure be
appreciated!
