This blog runs, like so many others, on Wordpress. Recently I’ve noticed some strange behaviour.

When I posted an entry, it wouldn’t show up. Not at first, and sometimes not for a long time afterwards. The entry was there: you could see it if you followed the link, for example if you came from Facebook or Twitter, to both of which I automatically distribute.

Eventually I did a bit of googling, and it turns out that caching plugins can have this effect. I had caching plugins installed. I disabled them, and suddenly everything was displaying normally.

You want to cache your content to help with the site’s performance. Cached pages should be served from the webserver’s filesystem, rather than generated from the content in the database each time they’re requested.

So I’ll need to investigate getting a plugin that isn’t problematic, but for now, if you’ve noticed anything odd about the site, it should all be be OK again.
