USPS Error

Hey all,

Can't seem to find an answer to my issue on the forum. Maybe I'm not looking hard enough - I really don't know. Anyway, my USPS shipping module doesn't appear when I enable it. Other methods work without a problem - but no dice for USPS. I'm all set up with USPS Web Tools, and they assure me that my account is activated on the production server.

The error I'm getting in my log is:

PHP Notice: Error: Unknown column 'unit' in 'where clause'<br />Error No: 1054<br />SELECT DISTINCT weight_class_id FROM oc_weight_class WHERE unit = 'lb' in /home/tinmust/public_html/store/system/database/mysql.php on line 49

Could someone please translate for me?
Has anyone had this issue before?
Anyone know the solution?

Thank you!

what version of opencart

Hi there - It is Version 1.5.2.1.

FYI - I reinstalled the USPS module and I think I got it to work!

I'm getting the same error message. I tried reinstalling it, but it's still not working. Help Please!!
