It's apparently conflicting with Shopp, which is also using Authorize.net. When I install the GF add-on my site errors out with </p> <blockquote><p>Fatal Error: Cannot redeclare class AuthorizeNetARB in /wp-content/plugins/shopp/gateways/AuthorizeNet/Authorize.net.php on line 393</p></blockquote> <p>Someone else had the same problem at <a href="http://www.gravityhelp.com/forums/topic/authorizenet-settings-fatal-error-cannot-redeclare-class-authorizenetarb" rel="nofollow">this link</a> but I'm not much of a coder and would like to find a way to correct this in GF rather than dicker around in Shopp. </p> <p>Any help certainly appreciated!</p> <p>-Anthony </p>
