Was also having this problem with the Stripe payment gateway and Balbooa Forms. I had an older version installed and thought it was this reason why it would not process credit cards with Stripe. I uploaded your latest version (v2.1.3.1) and to my surprise, same problem! Could not process credit cards through Stripe with Balbooa Forms. The only way to get this process to function properly was to download the ZIP package you mentioned earlier and FTP the form.php file to the website. Once I completed this, I was able to process credit cards using the Stripe payment gateway. With this I have a very important question... "Why am I, the customer, having to patch the latest release of Balbooa Forms? Should not the 'latest' release of Balbooa Forms have this patch already incorporated into it?" I'll await your explanation and/or an upgraded release. p.s. my subscription expired in 14 days so this needs to be resolved by then. Thank you!
