This is NOT fixed in WordPress 3.4.1, sadly.

I will confirm that live preview works in the base domain of the multisite install. For example, all my domains are based upon https://mypencil.net, and the live preview works there. It does not work on any of the subdomains (https://glenc.co, https://broadpool.com), however.

I had thought that it might disagree with the domain mapping pluging, but disabling that did not change the behavior.

Doesn’t work for me, either; also multisite. Could they have shipped this without ever testing it in multisite mode?

Ok, figured it out —?You have to fun the setup from the Site Admin -> Domain mapping page. I never saw a notice for that, but ran across it in the readme.txt file (not very useful if you automatically update the plugin, IMHO).

Oops, the table wp_domain_mapping_logins does not exist. Wonder where that comes from?

I cannot login on any mapped domain:

[Tue Dec 29 10:51:15 2009] [error] [client 71.92.250.150] WordPress database error Table ‘mypencil.wp_domain_mapping_logins’ doesn’t exist for query SELECT * FROM wp_domain_mapping_logins WHERE id = ‘a57ef13ca0b45b83cb29775a9775c835’ AND blog_id = 2 made by require, require_once, do_action, call_user_func_array, remote_login_js, referer: https://glencampbell.name/?dm_gotoadmin=1&back=%2Fwp-admin%2Fprofile.php

I get the “Unknown login key” whenever I attempt to login; this is after upgrading to 0.5.

This started when PHP upgraded to 5.2.1 and is still broken

This seems to have started when I upgraded PHP5 to 5.2.1 under FreeBSD 6.2 (same version/platform as yours). Seems to be very unstable as well. I think it may be tracked to pcre, the Perl-compatible regular expression library, but I don’t know enough of PHP internals to find out. preg_replace() calls the pcre, I think.
