Hi,

Just created a new square app in the square dashboard, gone to my site and installed the square extension and I am trying to connect to square but keep receiving this error.

"Notice: Undefined index: access_token in /homepages/1/d780133872/htdocs/P2A/admin/controller/extension/payment/squareup.php on line 633Warning: Cannot modify header information - headers already sent by (output started at /homepages/1/d780133872/htdocs/P2A/admin/controller/startup/error.php:34) in /homepages/1/d780133872/htdocs/P2A/system/library/response.php on line 36"

This question was asked multiple times. Short version: wrong response or error is returned from Square. With proper response an access token is returned.

In addition to the above, no OC version posted; forum rules.

The most generated errors being found on Opencart forum originates from contributed programming. The increased post counters are caused by redundancies of the same solutions that were already provided prior.
