It appears as though after the latest Litespeed upgrade my WPMU installation with Donncha's domain mapping plug-in isn't function correctly.
There is one domain mapped and the homepage at that domain loads fine, but nothing else -- 404 errors on everything. The whole thing seems to have started by a server error 503... and gone downhill from there. The other domain (not mapped) works as normal.
This is my host's diagnosis: "It seems like it's something to do with honoring the .htaccess file over a symlinked site. It's therefore not acknowledging the rewrite rules..."
He tweaked the server config file manually to redirect traffic and it's working normally.
No word yet from Litespeed. Anyone else experiencing this? We had very significant downtime from this -- since the homepage loads fine my uptime monitors didn't catch it...
