Hi, since WP 2.1, tested on WP 2.1.2 also, some posts lose their custom fields. I use them for storing META description and keywords with Another WordPress Meta Plugin.
Last night I updated to 2.1.2 and added keywords and descriptions again for all posts that were missing them. They are stored as custom fields.
24h later two posts have lost them again. They were the posts getting comments.
I'd appreciate any help resolving this one ...
