Do you have the Markdown plugin activated? Exactly the same thing happened to me today (out of the blue – I upgraded earlier in the week and things were fine then). I de-activated Markdown and the content shows again (unformatted of course). There doesn’t seem to be a newer version of the plugin available, so I’m not quite sure what to do from here.
That worked for me, though I had never knowingly activated the plugin before. Maybe it was on by default? All good now. Simon, try it out. I’m going to see if I can connect with the plugin developer.
Ok so you’re telling me my plugin could be the cause. Without more specific information it’ll be difficult to find the culprit however.
What would be useful is the server log which may contain the errors that caused this. Other helpful data would be the actual HTML page given by WordPress when the problem arise, a list of the active WordPress plugins you have, and the PHP version on your server.
MichelFortin: OK, I’ve been playing around a bit more, and decided to install your Markdown 1.0.1c version (I had the 1.0.1 Extra version before). I enabled it, and everything now works fine, with the contents being rendered and formatted properly. The weird thing was that I had 1.0.1 extra running before with no problems at all, even after the update to WordPress 2.0.2. It just suddenly went haywire, without me having fiddled with or changed anything in the intervening time, which made me doubt that your Markdown plugin was really to blame. However, turning plugins off and on in succession revealed that with every other plugin de-activated, turning Markdown on caused the problem and turning it off stopped.
Since it’s now ‘fixed’ on my site, I can’t easily provide the HTML, but I can tell you that the entire page was rendered properly except for the body of the post itself and the body of the comments. So the header, sidebar, title of the post and metadata all rendered properly, but there was just no content inserted at all (it was blank in the source too, with just the div tags that normally wrap the content itself present).
I have the following plugins active:
Amazon media manager 1.5
Get Recent Comments 1.2
Spam Karma 2.2 r2
PHP 5.1.2 (cli) (built: Apr 20 2006 07:18:35)
I’m really glad that it’s working again, because I really missed your plugin! I hope that this information helps, though it’s a really weird problem.
I had the same problem with the missing content after moving my site to a new server. Installing the lastest Markdown plugin fixed it.
