We’ve got a couple behind-the-scenes issues occuring with the website — our cache program isn’t working, sometimes the comment form seems to disappear, and there is an elusive bug with my permalinks. I’m working to fix all of these issues, so if you experience any system wonkiness, please bear with us!
UPDATE 1: The cache turns out to be functioning normally after all. A previous version would put TWO lines into the cached file indicating that it was served from the cache and the documentation still indicates this. However, the author has removed the second line, which is what I was looking for to determine if it was working.
UPDATE 2: It appears that the comment form issue is related to the page rendering in Internet Explorer or Firefox. The comment form works fine in Firefox, but not in Internet Explorer. We’re still working on this.
UPDATE 3: Thanks to Yosemite and Moshu from the WordPress Support forum (link above), we isolated the comment form problem to an out-of-date version of the HashCash plugin we’ve been running. Curiously, when I updated HashCash from 2.3 to 3.2, the comment form displayed properly in IE but not in Firefox — the opposite of what was happening before! As a result, I’ve disabled the HashCash plugin.
Still working on those permalinks! I’ve been directed to the documents that I believe will help. I just haven’t had time to work on it yet.
