One *very* last thing please(you have been more than helpful !!):
Having this:
WSGIDaemonProcess clientele user=nikos group=nikos home=/home/nikos/wsgi
WSGIScriptAlias /clientele /home/nikos/wsgi/clientele.py
process-group=clientele application-group=%{GLOBAL}
I cannot see to get a proper response when my app.py tries to load
http://superhost.gr/clientele
if page in ('clientele', 'downloads'):
try:
r = requests.get( 'http://superhost.gr/' + page )
if r.ok:
pdata = r.text + counter
else:
pdata = r.status_code
except:
pdata = "Error retrieving webpage!"
Just this one please and iam done asking you!!
