Can't log in to Admin site...no error message

I'm new at this and I've pretty much mucked the entire thing up!

I started by not putting the ZC files in the appropriate directory to begin with, which made both my ZC and my main site attempting to occupy the same space at the same time.

After attempting to fix this, I finally gave up and re-installed ZC in the correct location. This required creating a new admin page.

Now, I can log into the old ZC admin page...everything is still there.

But I cannot log into my new admin page. There is no error message...it just keeps reopening the login page. I've attempted to use incorrect info and I get an error message...wrong username or password. I've had my password resent. But I'm still unable to log in.

When I enter the page info on the web, I can access the site that I created last night...the new ZC...so the info is out there, somewhere.

I think I used the same user name for BOTH admin pages.

I went to the OLD admin page and changed my username. Still can't log in to the new one.

If I can't figure this one out, I'm thinking of starting over...again.

But, I'm not sure if that would help. If I were to delete the entire /store/ file and recreate the directory reload ZC to that file and start all over again with a different username and password, would that even work?

Any ideas? I put so much work into the old ZC page only to start all over again. I'm completely lost and have no idea where to go from here. I've tried to find a customer service/help line number to call, but I haven't had any luck.

HELP!!!!!

Check your admin configure.php files and see where the sessions are being stored. If they are in the database, log into your preferred MySQL manager (PHPMyAdmin etc) and empty the table zen_sessions (where zen_ is the prefix for your tables if you set them). Clear your browser cache, close and restart your browser and try again. If that doesn't let you in, change the session store option in the configure.php file to use file based sessions. You'll need to point it to a writeable folder on the server.

Either option allowed me to access the admin area for a site I've just transferred between servers.

I just moved my site over and upon admin log-in I get the following:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home2/glovenca/public_html/s_cart/davesadminforeds/includes/classes/logger.php:127) in /home2/glovenca/public_html/s_cart/includes/functions/sessions.php on line 108

I used the fix_cache_key.php file but still the same.

Can someone please help?

There are 63 lines to the file:
/admin/includes/classes/logger.php

This sounds like you might have a space or blank line at the end of the file after the closing php bracket ?> that needs to be cleaned up ...
