If you use Internet Explorer, there’s a good chance that 15-30 seconds after opening my blog you will get an “Operation Aborted” box pop up. Just close the box and hit the back button to read the blog.
I wasted most of yesterday trying to figure out what had happened to my blog. I deleted the last two posts, a sidebar poll, and turned off a third party add on that I thought might have caused the problem. But the problem persisted.
Later in the day it became evident that several, but not all, bloggers were encountering the same problem. See Blogger Help Group.
According to Known Issues for Blogger:
Some users are seeing an 'Operation Aborted' error message when trying to load their blogs from Internet Explorer. We're looking into this and will update this message when we have a fix.
We apologize for the inconvenience. — latest update on Thursday, May 21, 2009
