mohankirar Posted November 21, 2009 Share Posted November 21, 2009 Hello, I am new to USPS. I added it to my site and also gave userid and password (in admin section) same that i use to logon to USPS(usps.com). While checking out I am getting 'An error occured with the USPS shipping calculations. If you prefer to use USPS as your shipping method, please contact the store owner'. I do not know what to do. Any help would be greatly appriciated. Regards, Mohan Quote Link to comment Share on other sites More sharing options...

speedking Posted January 21, 2010 Share Posted January 21, 2010 Did anyone ever find out how to fix this problem ? Quote Link to comment Share on other sites More sharing options...
ztwistbooks Posted January 21, 2010 Share Posted January 21, 2010 This message shows up for any error. The usual cause of this problem is that you have not asked the postal service to move your account to production. The test server doesn't work at all, for anything.
