"How Long Until Blogger.com Contacts Me After I Report My BX Error Code Problem?"

According to one of Blogger.com's articles they don't generally
contact someone UNLESS they need more information about what it is
that you are reporting.

Also too, enough people have to report the error and I am assuming
that this is because Blogger.com has said that a lot of these bx error
codes are temporary - meaning you might want to give it a few days to
see if the problem solves itself.

It has also been suggested by one of the Blogger.com employees that
you might want to try to clear your cache and cookies and then re-load
your browser. Some people have posted that this has worked for them.
