I had a similar problem with 5212 - there appears to be some problem
the following file. Or it could be something intentional going on that
just not bright enough to figure out.
On line #44 of
43: <h2 style="margin-top: 30px">Response</h2>
44: <b>Headers</b>: <%=h response.headers.inspect.gsub(/,/, ",\n")
I was able to do a temporary hack to get my error screens back by
line 44 to the following:
Headers: <%=h response.headers.inspect.gsub(/,/, “,\n”) if
and response.headers %>
Hope this helps.
