Title: Problem with Authorize.net AIM integration Last modified: August 21, 2016 --- # Problem with Authorize.net AIM integration * [teeray](https://wordpress.org/support/users/teeray/) * (@teeray) * [13 years ago](https://wordpress.org/support/topic/problem-with-authorizenet-aim-integration/) * Apologies for cross-posting with tcp forum, but I have not yet received a reply over there so figured I’d try my luck over here. * After setting up TCP with authorize.net AIM integration successfully on a 4-site multi-site installation, something’s suddenly happened and the final checkout does NOT forward to authorize.net for credit card capture and processing. The order works fine on the WP side – an email confirmation is generated – but something with the integration has gone wrong. * Note that this was working fine, however at some point I changed servers and it’s possible it stopped working then. * At this point, I need some ideas for where and how to troubleshoot as there is no comprehensive information in the documentation. As far as I can see, all the authorize.net information is correct, and everything is set up correctly on my side. * Thanks. * [http://wordpress.org/extend/plugins/thecartpress/](http://wordpress.org/extend/plugins/thecartpress/) Viewing 10 replies - 1 through 10 (of 10 total) * Plugin Author [Inigo Gonzalez](https://wordpress.org/support/users/inigoini/) * (@inigoini) * [13 years ago](https://wordpress.org/support/topic/problem-with-authorizenet-aim-integration/#post-3707638) * Hi, * Why you don’t set your site in debug mode? (wp_config.php set WP_DEBUG to true) * Best regards * Thread Starter [teeray](https://wordpress.org/support/users/teeray/) * (@teeray) * [13 years ago](https://wordpress.org/support/topic/problem-with-authorizenet-aim-integration/#post-3707708) * Hi Inigo, * Thanks for the tip – I’d forgotten something so obvious. * The issue is the following: * Fatal error: Cannot redeclare class AuthorizeNetException in /var/www/vhosts/ hostname.org/httpdocs/wp-content/plugins/thecartpress/plugins/authorize.net/anet_php_sdk/ AuthorizeNet.php on line 29 * It’s a conflict with gravity forms Authorize.net plugin, which is being used elsewhere in the site. Is there any way to eliminate this conflict? * Plugin Author [Inigo Gonzalez](https://wordpress.org/support/users/inigoini/) * (@inigoini) * [13 years ago](https://wordpress.org/support/topic/problem-with-authorizenet-aim-integration/#post-3707710) * Hi, teeray * I’ll take a look… * Plugin Author [Inigo Gonzalez](https://wordpress.org/support/users/inigoini/) * (@inigoini) * [13 years ago](https://wordpress.org/support/topic/problem-with-authorizenet-aim-integration/#post-3707711) * Hi, teeray * Please, Could you change a line of code to test this solution? * thecartpress/plugins/authorize.net/TCPAuthorizeNet.class.php, line 136 Change: require_once dirname( __FILE__ ) . ‘/anet_php_sdk/AuthorizeNet.php’; * to: if ( ! class_exists( ‘AuthorizeNetException’ ) ) require_once dirname( __FILE__).‘/ anet_php_sdk/AuthorizeNet.php’; * Best regards * Thread Starter [teeray](https://wordpress.org/support/users/teeray/) * (@teeray) * [13 years ago](https://wordpress.org/support/topic/problem-with-authorizenet-aim-integration/#post-3707714) * Hi Inigo, * Thank you – that worked. * How do I prevent this being overwritten in plugin updates? Also, I have the same issue with changes I’ve made to the buy button template – this is overwritten every time I update the plugin. * Thanks. * Plugin Author [Inigo Gonzalez](https://wordpress.org/support/users/inigoini/) * (@inigoini) * [13 years ago](https://wordpress.org/support/topic/problem-with-authorizenet-aim-integration/#post-3707715) * Hi, teeray * I’ve added this code to the core. About the buy button template you can copy it to your theme. You have modified simple template, isn’t it? * Best regards * Thread Starter [teeray](https://wordpress.org/support/users/teeray/) * (@teeray) * [13 years ago](https://wordpress.org/support/topic/problem-with-authorizenet-aim-integration/#post-3707716) * Hi Inigo, * Modified the template in the templates folder. Simply copying tcp_buybutton_template. php to my theme folder doesn’t seem to work. Is there a particular structure needed? Using wordpress multisite along with thesis. * Plugin Author [Inigo Gonzalez](https://wordpress.org/support/users/inigoini/) * (@inigoini) * [13 years ago](https://wordpress.org/support/topic/problem-with-authorizenet-aim-integration/#post-3707717) * Hi, * This is not the file to copy. That file uses “tcp_buybutton-simple.php”. This is the template that you can copy in your theme. * Best regards * Thread Starter [teeray](https://wordpress.org/support/users/teeray/) * (@teeray) * [13 years ago](https://wordpress.org/support/topic/problem-with-authorizenet-aim-integration/#post-3707718) * Inigo, * This doesnt enable editing the message that appears when an object is added to cart. Is there a template that governs that? * Also, is there a template that allows you to change the address order on the checkout screen? * Plugin Author [Inigo Gonzalez](https://wordpress.org/support/users/inigoini/) * (@inigoini) * [13 years ago](https://wordpress.org/support/topic/problem-with-authorizenet-aim-integration/#post-3707719) * Ah ok. * You only can change this text crating a mo file for you. At this moment you cannot change the address fields order. We are working to make changes in the checkout. * Best regards Viewing 10 replies - 1 through 10 (of 10 total) The topic ‘Problem with Authorize.net AIM integration’ is closed to new replies. * ![](https://s.w.org/plugins/geopattern-icon/thecartpress_fefefe.svg) * [TheCartPress eCommerce Shopping Cart](https://wordpress.org/plugins/thecartpress/) * [Frequently Asked Questions](https://wordpress.org/plugins/thecartpress/#faq) * [Support Threads](https://wordpress.org/support/plugin/thecartpress/) * [Active Topics](https://wordpress.org/support/plugin/thecartpress/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/thecartpress/unresolved/) * [Reviews](https://wordpress.org/support/plugin/thecartpress/reviews/) ## Tags * [authorize.net](https://wordpress.org/support/topic-tag/authorize-net/) * [payment_gateway](https://wordpress.org/support/topic-tag/payment_gateway/) * 10 replies * 2 participants * Last reply from: [Inigo Gonzalez](https://wordpress.org/support/users/inigoini/) * Last activity: [13 years ago](https://wordpress.org/support/topic/problem-with-authorizenet-aim-integration/#post-3707719) * Status: not resolved
