Dear Deian,
unfortunately I have the same problem. When I put the button code into my desired article, just the code text appears in the article, but not the button.
The content plugin for button display is enabled already - so this cannot be the problem in my case.
Following button code I try to include in my article:
{quicksell file="Rockabilly Kochschürze Schnittmuster.rar" price="3" title="Rockabilly Kochschürze Schnittmuster.rar" currency="" customPayPal="" emailDelivery="on" requireRegistration="" discount_rate="" return_url="" notification_email="" rm="" cbt="" sales_limit=""}Button_JetztKaufenMitPayPal_209x65.png{/quicksell}
Can you please help me to find my error?
Thanks and best regards,
Doreen
