This is a message  by a Google Employee:

"A bX code happens when there's an unexpected error on the Blogger backend. It can be any number of things, but the general pattern is that a bX code comes from an error that's probably rare enough that we don't have code to handle it gracefully. Instead, Blogger barfs, shows the bX code (which is like a fingerprint of the error, so we can look it up), and that's it.

Of course, sometimes situations arise where these very rare errors become common (a bug on our end, or some service we're dependent upon is undergoing maintenance) and are seen by lots of people. It's these cases that we have the http://bx-codes.blogspot.com/ blog for, which lets us instantly show a relevant error message on the bX code page, and any workarounds that may exist.

"Clearing cache and cookies" will almost never actually "solve" a bX code problem. The exact same effect would be achieved by just waiting a minute or so and re-trying.

Clearing cache and cookies helps with other problems, though, such as strange browser behavior when logging in, or a page not appearing or behaving correctly.

If you're faced with a bX code, and waiting and retrying doesn't work, my next recommendation would be to try and get more information (does this happen on other blogs? did you recently change your blog's template or settings?) and then see if people are talking about the bX code on the Blogger Help Group. If no one is, start up a new thread."
