@ses707:
I've posted your latest version, just in case someone clicks my link. Thanks for removing all the 'Return' items from SQL. Would you be so kind as to double-check the Page Registration? This process is new as of v1.5, and I haven't found much documentation for correct syntax.
@SPembleton:
Did you try the latest version by ses707? And, did you hit refresh while you were on that error page, or after you clicked the back button?
I think the error appears when there are residual configurations left from failed installations of this module. An alternative is to go into your admin_pages table, delete any rows for USPS AutoFill, and it might be a good idea to do the same in configuration table. Then install fresh files and run the latest SQL for your version of Zen Cart (click ses707's link above).
