To reproduce,

Go to Accounts > Customers > Customers > Press the "Login as Customer" icon

Now that you are logged into the customer portal go to Rates > Rates and Search MyRates by entering some area code and pressing the Search button. You will just get the waiting icon but it never finds a match. If you go to Chrome or Firefox developer console you will see a 500 error code. Clicking on the link beside that code you will see the following error.

A Database Error Occurred
Error Number: 1054

Unknown column 'pattern' in 'where clause'

SELECT pricelist_id FROM (`accounts`) WHERE `pattern` LIKE '^212%' AND `id` = '15'
