It looks like my WP blog has been hijacked. Visitors land on my blog...and are then redirected to one of a number of other sites. I upgraded to 2.9.1 and got the same issue. Here are a couple of the redirects: http://mx3.33544.blueseek.com/jump2/?affiliate=mx3&subid=33544&terms=komodo http://mx3.33544.blueseek.com/jump2/?affiliate=mx3&subid=33544&terms=mitsubishi etc, etc. etc. This happens from different computers so it's not an issue with my personal PC...it looks like an issue with the WP config itself. Any help would be very much appreciated!
Update: turns out it was a PHP injection issue with my WP theme. I replaced the theme with a fresh copy and everything works again. Hope this helps someone else.
Thanks a lot! I've just gone to one of mine and found this little rascal running .... if it hadn't been for your post I'd have messed about fruitlessly for hours! I never did like the theme I was running, time for a new one I think... good enough reason to change!
