I uploaded the lastest nightly tonight hoping to fix a problem I had with my 01/01 install of 1.5 Beta. I didn't... so I had to do some digging.
I got my site all the way I wanted it and found a weird problem. I reverted all the way back to the default install of WP with the default theme. (even installing it on a new site and trying it there)
If I used the < more > or < Next > buttons in a "page" they would work on a default install of WP, but not if I set a date structure in my permalink options. I removed the Permalink settings and it started working again.
Any thoughts on that?
(I thought I broke it with a tweaked Kubrick template, but it wasn't me... ;-)
