I downgraded all folders and files except the content folder back to WordPress 2.9.2 for my comment-recuperer-mon-ex.com site for which I have been using the Alkivia Chameleon theme. That’s resolved the problem for now.
I’ll wait till the Alkivia theme’s been updated defore I update my WP. I’ve got too much customization to be bothered with changeing the theme…
Some times, just saving the permalinks again solves this kind of issues.
This resolved this issue for me…
Thanks Txanny 🙂
