They used to work on our old server, but this one doesnt’t appear to like any of therm! I think it is most likely to do with permissions, but it may take some time to resolve. If I add the “wp-noteable” plugin, not only does the admnistration system dissapear, but so does the site!!! Some more investigation over the weekend should help.
I’ve also been working on some database wizadry to try to get one of our more presitigious sites more flexible, but no matter how easy you think things can be, they are always more complicated! Rats.
