Thank you all. My shop seems to be working properly again. There was an error in my Paypal information. Fixing the error did not solve the problem until I uninstalled the Paypal Module (again) and reinstalled it for the second time with the correct information. Thank you, thank you, thank you.

I reinstalled the Cart module and the Paypal module. At first both appeared to be working. Then A NEW customer attempted to use Paypal and produced this error:PayPal response: TIMESTAMP -> 2012-09-24T16:02:22Z L_ERRORCODE0 -> 10002 L_SHORTMESSAGE0 -> Security error L_LONGMESSAGE0 -> Security header is not valid L_SEVERITYCODE0 -> Error I attempted to by as buy as an existing customer and the Shipping and payment options do not load. Refreshed and they loaded but Categories disappeared so I can not buy any product. Any suggestions?

I have upgraded from 1.4 to 1.5. In the old version when add to cart was clicked the cart appeard with the product showing and the account registration form below. Now nothing appears to happen when the add to cart is clicked, but the product is added in background and can be seen with the form below by clicking the cart (empty) link on the top of the site. Very confusing for users. Many will click several times - then give up without clicking the cart (empty). Any help would be appreciated.

PayPal works in 1.5 If you have a problem with it after upgrading try uninstall then re-install

When I installed version 1.5 Paypal did not work. I used the Uninstal. Then reinstaled it. Works fine now.
