So I got it, only to discover that all the config fields were empty. Apparently version 1.6.4 has a bit of a problem with not prepopulating the fields with the proper strings and escape characters. Whoops.
Fortunately, Tris found a site that had a giant screenshot of the actual settings here. So in the event that you’re taking advice about the version 1.6.4 of the All in One SEO pack for WordPress, do check that out, won’t you? You’ll have to retype everything, but still, awesome.
I really don’t want to see this yellow “All in One SEO Pack must be configured” message at the top of all my posts, and hey, better SEO stuff would be super, too, so I’m fixing that right now.
If you’re not using it, you should be. More hits are better hits.
