I have set up a PayPal widget on my site www.ukcvwriting.co.uk and the widget works seamlessly on the build computer and takes me straight through to the correct PayPal sign-in page. I also checked the functioning on my office laptop (not used in the build) and this also works just fine. So far so good <!-- s:D --><img src="{SMILIES_PATH}/icon_e_biggrin.gif" alt=":D" title="Very Happy" /><!-- s:D --> .
I notified my client that the site was now operational only to receive an email saying that, on his computer, the PayPal button went straight to a PayPal error page. I have now tried (and asked friends to try) on an number of computers around London and, sure enough, they also throw up the same error page.
Yet when I try logging in on the build computer (I am using IE9 but have tried using Firefox and Chrome) all works perfectly with no errors whatsoever. In frustration I deleted the inbuilt Webeden PayPal widget and just used the 'insert HTML' option which worked (of course) perfectly on my computer but nowhere else.
So I am really, really scratching my head on this one. HELP!!!
I seem to have solved the problem by changing the type of PayPal button from a multiple option to a 'Basket' version. Somehow the addition of a separate page showing which items have been selected prior to porting to the payment page has done the trick.
I am no wiser but glad to have found a way around the problem.
