Need to say thanks to David for alerting me that the Pages in my blog had broken links – happened when I got rid of the permalinks. Sigh.
I found another error too. Went to my WordPress Dashboard and saw I had 4 comments that needed moderation. However, when I clicked on the Comments section, the "Awaiting Moderation" part was blank!
Managed to get around this by going back to my Dashboard – Manage Posts and under this section, posts that have comments awaiting moderation are highlighted a darker shade.
Sigh… I hope there’s a new release of WP 2.6 soon… with all these bugs fixed!
