Hi, thanks for responding quickly. The problem seems to arise when you go to my website via http://www.garyhobbs.co.uk (which is how most users will) and chose the page from the menu (It’s About You Online; Articles), whereas go directly to http://essexrubbishremoval.co.uk/garyhobbs/its-about-you-online/articles and it works. I thought this could be a problem with URL masking on secure sites (like Paypal) but I am able to link to Paypal successfully via http://www.garyhobbs.co.uk by using buttons produced by Paypal’s Website Payments Standard pages, which confused me even further.
(BTW I mentioned the add product to cart not always working as I thought this might be related to this other issue. Would you like this raised as a separate post to keep it easier for your forum searches?)
Gary
