I have built a shopping cart using joomla and virtuemart and it was working fine, but suddenly it has stopped letting registered users login.
Once the registered user logs in they get the following message:
Username and password do not match or you do not have an account yet
I can login as admin and add products to the cart, but not as a registered user.
I'm also having trouble getting the paypal option to work.
The website is - [url removed, login to view]
I need this fixed ASAP.
