I decided that it really was time I upgraded my installation of WordPress from version 2.2.1. This is normally a really simple porcess, but not this time.

Rather than overwriting the existing installation, I always start afresh. I backed up the databases as usual, disabled all plugins, downloaded the latest version (2.9.2) and then proceeded to incoroprate my edits into the new version. I also copied across the theme and plugins.

However, when I tried to run the upgrade script, I got the following error logged in Apache’s error_log [notice] child pid 19836 exit signal Segmentation fault (11)

After speaking to my Hosting company, they advised that they had had a lot of compatibility problems with PHP 5.3.0 and advised downgrading to PHP 5.2.12 instead.

All is OK now
