That's interesting. I used ;dm to download error logs and it seems the problem lies with this error message:
framework: [41m[PRE_RENDER] fillUpCache(533): ERROR: NO page cache list or current page is a special page that shouldn't use cache[0m
Any insights into what "No page cache list" might mean? (There's nothing special about the page, just plain straight text, so I don't think the second half of the error message applies.)

Thanks!
