Can't add users with Omeka.net account

I have "super" status and I'm trying to add contributor users to my site. However, I keep encountering "Omeka Has Encountered an Error". How do I solve this?

Thanks in advance.

We'll dig into the logs to see if we can find the error. What is your subdomain on omeka.net?

Thanks for looking into the issue, but it appears to be resolved now.
