Hello again!
i've faced with another related problem, and rely on your competent help
only!
recently, i've been posting my app. And when somebody calls my url, gets
"ERR_CONTENT_DECODING_FAILED" or curl_err:23
so i added SetEnv no-gzip 1 into my VirtualHost Directory.
it now looks like:
<Directory /home/user01/nano_fb_py_bot/nano_fb_py_bot>
SetEnv no-gzip 1
<Files wsgi.py>
Require all granted
</Files>
</Directory>
funny thing is, when now somebody requests url, he gets
%valid content%
*Internal Server Error*
the server encountered.....blah-blah-blah 500Error
in the apache log i see the same *Truncated or oversized response headers
received from daemon process*
any ideas on that Graham?
