The site works fine local, setting up in "production" following the steps form: http://cookiecutter-django.readthedocs.io/en/latest/deployment-on-pythonanywhere.html

The /var/www/myapplication_pythonanywhere_com_wsgi.py looks like below with the postactivate in the virtual environment looking similar 

> import os import sys path = 'home/myapplication/myapplication/' if
> path not in sys.path:

Of course running pip install mysqlclient or pymysql is says that the Requirement already satisfied. Database seems to have set-up tables and everything ok so doesn't seems like an issue there

Any thoughts ? Any assistance would be greatly appericated

It might be a Python version difference. Your website is set up to use Python 3.5, and pip on its own will manage modules for Python 2.7. If you run 

pip3.5 install --user pymysql

....then that will install the module for the right Python version.

thanks thats working now ... well almost, hoping you might be able to assist a little further Just an issues with the static files now. Getting an error 500 on my static files.

My production.py has this set 

STATIC_ROOT = "/home/myusername/myapplication/static"
STATIC_URL = '/static/'
STATICFILES_DIRS = [
    str(APPS_DIR.path('static')),

And on the Web application set url as /static/ and path from STATIC_ROOT

All seems to work fine when i run the collectstatic command runs through and gives 1468 static files copied to '/home/myusername/myapplicationname/static'.

Any thoughts?

Sorry for the slow turnaround on this! I suspect you might have moved things along since your last post, but I can see a different (and more helpfully-formatted) error in your error log right now -- it looks like you need to add something to your settings...?
