All In One SEO Pack 1.4.7.3
WP Super Cache 0.9.1

WP Super Cache supports server-side compression which you’d think is a good thing.  It doesn’t seem to play nice with the All In One SEO Pack, though.  You’ll need to turn compression off and delete your cache to get the two to work together.  Funny trade-off, though: if you’ve installed the SEO pack then you obviously want to increase traffic to your site.  Assuming this works, it would be of benefit to have server-side compression working to reduce the load on your server.

As an aside, I like the second comment on this forum posting:

“Why are you using crap like Super Cache anyway? Get rid of it entirely. Get 1BlogCacher — it’s simple, it works without problems, and it’s very, very good in making your blog static. And yes, it works with all other plugins without trouble.”

I assume he’s referring to a different caching plugin.
