On Checkout when USPS active - Blank Page...

[bmasella]

When I have the USPS shipping module turned on with my information installed and using the production server (I just verified this with USPS this morning.) I get a blank page after a lengthy delay when I should be seeing the shipping choices page of checkout.

If I turn off USPS then the other shipping choices show just fine... leading me to believe that it is a problem somehow tied to the module or how I have it configured....

Can anyone help? Maybe shed some light?

Check your error logs on the server. Blank page usually means a php error, that will be reported in the error log.

Start there.

Checked the Error logs and they were blank.

It is only when I have the USPS module turned on that it happens.

I could never get it to work on the test servers... Had them switch me to live a few days ago... called to confirm that I was on the live servers and they indicated that was the case.

Verified login and password... still nothing.... Decided to be safe and cut and paste them from the USPS email. Nope... still not working...

Checked to make sure that the usps module had the correct server address for the production server.... it did.

Don't know what else to check for.
