Login widget doesn't think we're logged in but WP does

We recently upgraded from am3 to am4 and went with the amember widget included with am4 to show a login form. We can login, but the login form still shows when we're returned back to the page we logged in from instead of our subscription links etc. Its a little odd because wordpress seems to know we're logged in. Could it be a cookie issue because we're running amember on a separate sub domain?

For example:
http://members.example.com (amember)
http://example.com (wordpress)

We did this because the instructions for a wordpress install discourage putting amember in the root of the wordpress website install.

Thanks,
Gary

Maybe it isn't a cookie issue. I just inspected the cookies and noticed the same hashes on both domains. I'm not sure what else it could be.

I found that moving amember into the primary domain as a sub directory fixed the issue.

That would explain it! Thanks... will give it a try.
