When I comment on a blog post I get a 404 “page not found” error. However the post has been made, so the problem occurs after submitting. (broken reference back to the page? some other after-submitting process going wrong?)
@bram – I’m familiar with the problem, it happens when I tinker with certain files and can confirm the issue. I’ve since rebooted the server and cleaned up some code in one of the files that writes the URLs, I tested it and it seems to be working.
Can you test and confirm that it is working properly now?
Try clearing your cache, I’ve not seen the issue. I tested on the blog linked above an everything worked fine. The rules that handle it have been flushing across the network all afternoon (every time someone visits a dashboard, the URL rewrite get flushed – those rules are what causes the problem). I’ve going to leave the flushing script on for another 24 hours or so, though I think that clearing your browser cache should fix the problem.
