Bizarre Linux-WordPress-PodPress issue
As there are legions of pages out there on the various “blank page” errors in WordPress, I’ll add my own experience here, in the hopes of helping others.
I run, on behalf of a client, a wide array of WordPress blogs using the excellent PodPress podcasting plugin.
Some of those blogs suddenly started experiencing the dread “blank page” error. The logs were unhelpful, reporting a 304.
The problem wound up being a bunch of MP3’s (the podcasts) that another contact of the clients’ had uploaded for them, that wound up in the /tmp partition.
One quick “rm -rf /tmp/*.mp3″ and everything was good to go.
I hope this is helpful to others; I know how many blind alleys I stumbled down trying to properly troubleshoot this issue. In the end, I just happened to notice 100% utilization of /tmp as I was checking the RAM usage. Troubleshooting this error is unfortunately made more difficult by a wide range of red herrings.
