Hello!
I use the Sage Notebook on my server with Sage v.7.4. And each time I try to
open some TXT file in the DATA folder I get the error message in the web
interface
500: Internal server error.
And in the terminal where I started the Sage server, I see this error message:
==================

==================
I tried to play with the LANG environment variable, as some people on the
StackOverflow suggested, but did not succeed.
So is it some bug in Sage or is it because of some incorrect configuration of
my server?
Thanks!
