Log on to your GoDaddy hosting account and click "manage account"
Go to databases and select your store's database
Click "manage via web admin" and log in to the database
Make sure the directory tree on the left is expanded until you see "tables" and click on it
Find the line that says nop_customer and click the "edit" icon on the right of this line. Hover over the icons to make sure you have the correct icon. You do NOT want to accidentally delete this!
Find the line that contains the email address that you are trying to use to login as the administrator and click the "edit" icon on the left end of this line
Scroll down to the "is admin" box and make sure the number 1 is selected.
Click the save button.
If this doesn't work, I would just log in to your online store as a new customer and repeat the whole process for the new account you just created.
This is what I had to do when I first installed 1.3 in order to have admin access (even though I used "[email protected]
and my database password)
Hope this helps!
