Transfered modx site to a new domain, running into a big problem

I moved a modx site to a new domain, and I updated what I think are all the config files with the new path. The site is working, it seems to be working fine. And I can log into the manager, but I can't do anything. All the right information and resources displays in the box on the left, but on the right, there is no dashboard or anything else, just this message:

Could not find action file at:(right here is the old part of the file path, not the new one)/manager/controllers/default/element/snippet/update.php

Where do I give Modx the new path for that file it wants?

Hello,

You have to clear or delete core/cache files

Check all config files in Modx directories and see if old paths are still present, update to new paths

You have to edit System Settings fields manually in the database of your new domain or host

FInally flush all sessions and permissions in the manager

Log out, clear your browser temp files and login again.

Hope this helps.

Thank you for your response. I checked all the config files in the modx directories, that I am aware of at least. All the config files listed here, http://rtfm.modx.com/display/revolution20/Moving+Your+Site+to+a+New+Server, at least. I flushed sessions and permissions and cleared the sites cache, and I dug through the database for any trace of the old file path, and I can't find any. The darn thing is just stubbornly holding onto this one instance of the old file path, and I don't know why.

The value for path in my workspaces table is set to a variable, {core_path}. Should I manually set that to the new path to the core folder?

I just deleted everything in /core/cache/ and it seems to be working great now!!
