1. While disabling the plugin SABRE, all my posts were deleted by a bug. The SABRE plugin author tells me it can't be his plugin. Could it be a bug in WP 2.5?
2. Just after publishing a post, I pushed the backward button on FireFox to return to my draft (a stupid idea, I know). My system ended up with both the published post and a broken draft, with the same content. (An attempt at deleting the draft ending up deleting the published post, too.) I managed to solve this problem by re-instating a previous version of my database.
Any idea, folks?
