ERRORs 2 and 3 fixed:

User pages now deal with strictly user content; likewise with stores pages. HTML is showing now- changed base.html to accountsbase.html and storesbase.html, which then extend to their apps, respectively.

Still can't create store objects via the form- django.core.base.py is throwing an exception: Inoperable types int() and str(). This error is traced back to the get_response() in django. There must be a problem with the params from the StoreCreateView class.
Store creation error fixed; changed accounts.models to fix error.

Fix-----
from:
store_name = models.CharField(max_length="50")
 to:
store_name = models.CharField(max_length=50)

Hence changing the erroneous str() to an int(). Yay!
