[Plugin: WordPress MU Domain Mapping] Error: You are not allowed to be here

If Domain Mapping’s option to “redirect administration pages to site’s original domain” is not checked, then some plugins seem to generate the error “You are not allowed to be here.” when attempting to use them.

That message is being generate by WP security. If your user logs into both the unmapped and mapped domain they should not see that error message. The DM plugin will not be altered to bypass WP security.

Logging into both domains seems like a cumbersome solution.

Perhaps the problem is with the individual plugins and the solution needs to be implemented by those developers.

But given that it’s more than one plugin, I thought the DM team might want to know about it.

I found something that may also be of use to anyone else having similar problems.

I noticed in my DM settings for this particular site, I still had the domain set to subdomain.mydomain.org when it really should have been customdomain.org

Updating that setting resolved the error and I do not have to check the “Redirect administrative pages to the original url” option.
