EDIT: Now they seem to be working again, with no action on my part and no known software updates through the whole process. Go figure. I do not know WordPress well enough to guess just exactly what had to have been broken and then fixed at my hosting provider to have caused these effects.
As of this writing, my blogs (DBMS2, the Monash Report, Text Technologies, and Software Memories) are all working in Firefox, and the top page of each is working in IE, but the rest of the pages/links are NOT working in IE. (But www.monash.com, a non-Wordpress site on the same host, IS still working through IE.) Naturallly, I’m addressing this problem as fast as I can. I imagine the fix will involve some sort of a reinstall and/or theme change, which could alter the blogs’ look-and-feel, maybe not for the better (especially at first). I apologize for the inconvenience!
