It's a EE multi-site, and I suspect that has something to do with the error, but not sure. I have 'msm_show_all' set to true in the config file. This is the error I get when any CartThrob link is clicked in the admin area:
"The account you are attempting to access does not exist."
But under add-ons -> modules it says it is installed successfully.
Any help would be appreciated.
