when filling out a form / placing an order, you get as far as editing the cart. When you click on checkout or paypal it just refreshes the edit cart page
Can you check the Store URL (and HTTPS URL) in the main admin settings page and make sure they match the URL structure of your site ie that the use or not of the "www" in all is consistent?
Thanks Andy I new it was something simple I had missed
Now when I click on the checkout button it works - Collects name address ect then goes throught to paypal and completes the transaction
But when I click on paypal button instead of checkout it takes me to a 404 error page on Paypal How do I remove the paypal button just leaving the checkout?
That PayPal Express button shouldn't go to a 404 page but to remove the button from the first cart screen, go into the payment provider admin page and uncheck the "Enabled" box for PayPal Express Payments.
