I would like to change the Paypal image for a simple CSS button. In the file instantpaypal.php, I changed this line code:
<input type="image" name="submit" style="border: 0;" src="' . $btnimgview . '" alt="PayPal - The safer, easier way to pay online" />
<input type="button" name="submit" value="Buy now" />
But the link to Payl seems broken, no redirection to paypal cart when clicking on it. Everything works fine with the default instantpaypal.php file (free version).
What could be the issue?
