Ok. I think I fixed the problem. Sorry for the delay.
First I noticed that the Acadec blog still worked, and other people’s blogs still worked, just not ours. Ours? All the ones under the subdomain blog.mrlocke.net. The acadec blog is under the subdomain acadec.mrlocke.net.
I basically saved all the files in the subdomain (including all your blogs), deleted it, and re-created it. I’m not sure why or how that fixed things, but apparently it did.
Let me know if you have any more problems, and blog your hearts out…
