Recently WordPress shipped an update to their fine blogging engine. The version that had been in use for this blog was capable of performing an automatic update to the new version. However, no matter how many times I clicked the “upgrade” button the upgrade would just never execute. Some searching around the WordPress forums led me to a listing of web hosts that needed a few adjustments. All that was necessary to enable the automatic upgrades was to tell the host via the .htaccess file in the main WordPress directory that PHP5 should be enabled.
AddType x-mapp-php5 .php
