Patrik and Guust,
Thank you both for your time and efforts but i think the issue is now resolved.
The settings for the checkout page was set to the old “WPGEO Checkout” page the wpinvocie shortcode was not on it.
Not sure how the checkout page was loading and the stripe payment form was poping up, maybe because the old stripe plugin was loaded???
Any way i created a new page with the wpinvocie shortcode on it and removed the old wpgeo stripe addon and all seems to be working now.
Thanks once again
