Thanks to a number of readers who emailed me to say that they were having problems accessing the Gruts website. Internet Explorer browser users were particularly badly hit. Yes, I know, serves them right—but, in this case, it looks as if it wasn't Internet Explorer's fault.
I believe I've fixed the problem. For the technically inclined amongst you, Keith, it looks as if it was down to a popular WordPress caching plugin which can end up writing to the .htaccess file. Totally uncoincidentally, I am sure, the plugin in question went through a major upgrade earlier today. I have now re-configured the plugin so that it doesn't write to the .htaccess file, and, touch-wood, normal disservice seems to have been restored.
Update 06-Dec-2011 18:45: Apparently, now the Gruts post permalinks aren't working properly. That'll be due to my 'fix'. I'm looking into it now. Fixed!
