Hello,
I installed Askbot locally following the documentation step by step.

When I run Askbot using python manage.py runserverhostname -i:8000 everything seems to work fine but using the above apache configuration it seems to end in a neverending loop. The output of the log is:

tail -f /var/log/apache2/askbot_error.log 
mod_wsgi (pid=31580): Attach interpreter ''.
mod_wsgi (pid=31580): Imported 'mod_wsgi'.

mod_wsgi (pid=31580, process='askbot', application='askbot.localhost|'): Loading WSGI script '/var/www/html/askbot-devel/django.wsgi'.
Script timed out before returning headers: django.wsgi

But it wont go any further and the site wont stop loading...

Any idea why and how to solve it?

Hi Marc, could you put a hint to solution here please?

[ghost]

Well I seem to got it to work for some time until it stopped suddendly again. Currently trying to find out why but the problem were some missing requirements and some errors with the virtualenv. I updated the install script above.

[evgenyfadeev]

Does "python manage.py runserver" command start a working site?
If so then the issue is in the deployment

[ghost]

It did before, right now it doesnt do anything anymore. Using the runserver will load forever and no output on the console.

[evgenyfadeev]

Then solve the problem using the runserver, this also allows you to use debugger more easily.

[ghost]

Yes I would unfortunately the runserver wont run ;) Thats my problem right now. I might try to set it up from scratch again to test if I changed something by accident since last time.

[evgenyfadeev]

It does run, but gets stuck somewhere. If you insert a debugging statement you can step up to the point where it hangs.

[ghost]

Seemed to be some kind of permission problem. Now it is running and just returning the 3 usual warnings (Already opened issues for them).
But now the apache-deployment doesnt like me again...
It will go to Target WSGI script '/var/www/html/askbot-devel/django.wsgi' cannot be loaded as Python module
Might try debugging more now...

Edit: Okay fun fact: As soon as I try running the apache server and triggering the error the runserver command will stop working as well

Edit: The error seems to be in this line application = get_wsgi_application()

Edit: Tracked it to execute_from_command_line(sys.argv) in manage.py (Variable is set correctly)
If I try to put debug command into this function it wont return so something seems to be wrong with that..(python manage.py help gets stuck as well)

[evgenyfadeev]

Look into log files, in those cases you just need to chown some files.
