Php PayPal标准支付沙盒显示空白页

我使用贝宝标准支付和使用以下代码

<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">  
    <input type="hidden" name="quantity_1" value="1">
    <input type="hidden" name="item_name_1" value="Sasha">
    <input type="hidden" name="amount_1" value="545.71">
    <input type="hidden" name="business" value="<merchant-email-id>">
    <input type="hidden" name="cmd" value="_cart"> 
    <input type="hidden" name="upload" value="1">  
    <input type="hidden" name="currency_code" value="EUR">
    <input type="hidden" name="address_override" value="0"> 
    <input type="hidden" name="custom" value="48"> 
    <input type="hidden" name="first_name" value="test11">
    <input type="hidden" name="last_name" value="test21">
    <input type="hidden" name="email" value="<buyer-email-id>">
    <input type="hidden" name="address" value="Santa clara">
    <input type="hidden" name="city" value="Santa clara">
    <input type="hidden" name="state" value="CA">
    <input type="hidden" name="zip" value="95050">
    <input type="hidden" name="country" value="USA">
    <input type="hidden" name="phone" value="1023456789">
    <input type="hidden" name="notify_url" value="<complete-url>" />
    <input type="hidden" name="return" value="<complete-url>" /> 
    <input type="hidden" name="cancel_return" value="<complete-url>" />
    <input type="submit" value="Submit">
</form>

当我按下submit并转到PayPal沙盒屏幕时，它会显示空白页面。是在维修中，还是我这边可能有问题。几天前，同样的表格还在运行，但从最后3-4天开始，PayPal沙箱页面显示为空白

我不明白这是我这边的问题还是他们那边的问题？

注意：-请在上面链接并使用此表格。并检查结果或检查下表

同样的事情也发生在我身上。它在控制台中显示内部服务器错误。读取。他使用

sandbox

而不是

live

。所以您可以将其url检查链接更改为live到sandbox:-您可以读取问题吗？他用了沙箱，但它不工作。是的，杰德普，你说得对。我的问题是沙盒。在现场模式下，它已经可以正常工作了。
