I was having a strange issue recently on this blog – occassionally a blog post would 404 when the PermaLink was clicked on – the post would appear fine in the blog’s main page but any attempt to view it individually would fail! Deleting the post and re-posting with a new title solved it, so some part of the title seemed to be causing the problem.
This happened twice in the last couple of weeks – both times with podcast interviews posts. This got me thinking – I checked the mp3 filename and in both cases the mp3 filename was the same as the post title (i.e. darren-barefoot-interview.mp3 in a post entitled Darren Barefoot interview). Again, another solution, if you come across this issue is to re-name the mp3 file – this should have less impact than deleting posts and re-posting under a new title.
Finally, being aware of this, come up with a procedure to ensure that your post titles and files don.t share a name and it should no longer be an issue.
