I have similar code that is both on sandbox and production
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="upload" value="1">
<input type="hidden" name="business" value="xxxx">
<input type="hidden" name="item_name_1" value="item1 />
<input type="hidden" name="amount_1" value="123"/>
<input type="hidden" name="currency_code" value="CAD">
<input type="hidden" name="no_note" value="1">
<input type="hidden" name="return" value="http://xxx">
<input type="hidden" name="rm" value="2" />
in the user profile, auto return is on and PDT is off on both sandbox and production.
In production, the auto retunr works and payment detail is in the post.
In Sandbox, it was working before Aug 7, since then, it always return to the url specified in the url variable in http get but with no data.
Is there something wrong with sandbox?
