We have a number of people Blogging on a site.
When someone adds an external Blog feed, next day (after Cron) any entries made on the site (rather than imported from the external site) are deleted!
I've seen this 'disappearing Blog entries' happen twice now, and on both occasions it was just after someone added an external Blog feed.
I've suggesting setting the Priority of this bug to a Blocker - because if sites are using Blogs as an assessment tool (e.g. a reflective diary) this loss of data could have a major impact.
I'm happy to give developers Admin access to the site affected, or phpMyAdmin access to the database.
