I have a few of my blogs running on Wordpress 1.4 with the WP Cron and WP Database Backup plugins working perfectly, I would get an automated email everyday with a backup of each of my blog’s databases.  Thanks GMail for all the space

Well, I recently upgraded my blogs to WordPress 2.0.4 and I stopped getting the automated emails.  The WP Database Backup plugin comes pre-installed with version 2.0.4 of Wordpress and my WP Cron plugin was left untouched.  I checked the versions of my old WP Database Backup plugin against the new version and they both were 1.7, so I initially thought that the WP Cron plugin was the issue.

I eventually debugged it down to the fact that the two WP Database Backup plugins (old and new) were different even though they both stated version 1.7.   So I overwrote the newer WP Database Backup plugin with my old backup copy of the WP Database Backup plugin and the emails started to arrive again with the blog backups attached.

The versions that work for me with Wordpress 2.0.4 are:

WP Cron

WP Database Backup

So I had to use the older version of the WP Database Backup plugin (not the version shipped with WP 2.0.4).  Disappointing that two different versions of the WP Database Backup plugin were both labelled version 1.7.
