I hate to hijack a topic like this, but I am experiencing the same problem as the originator of this message on a different website. The site in question is: http://www.yuribou.net/blog/ Specifically, it is when I try to go to the comments sections. This is the only website I am getting the error on, and I don’t see it on any other site. It also only pops up whenever I try to go to anywhere on the site other than the blog page, even the top of the domain. The odd thing is, it only started happening when the site owner upgraded to WordPress 2.7. Could this be causing the problem, am I getting a false positive? Or has the site been tagged? I have contacted the site owner, but have not heard anything back yet.
For reference, I am using SeaMonkey 1.1.15 (Released on the weekend) But it did crop up in my older version of SeaMonkey (1.1.14) as well.
