Error in paypal and 2checkout payments app.
I have a big problem in my store
to complete the payment of any product on paypal , returning to my shop, back again to the PayPal site to collect again.
payment is made for the first time without a problem but complete the process returns back to the page collection of paypal .
it doubles payouts my clients do and confused .
how do I fix it ?
does the same, when I use with 2checkout ,
I think something is not right in my store callback .
someone has a solution ?
return to my store checkout page is set to http : // mystore / checkout / sucess
but not working well . ,
