USPS Module (Free) never works for me

[nquinn]

So,

 

I've googled this issue and run into dozens of other people who seem to have this problem, but I haven't found a solution yet.

 

I installed the USPS shipping module (real time shipping), but it never gives me an option to use it, always prompting:

 

No carriers available for the address

 

Now, I've tried LOTS of things:

- Switched from one-page checkout to 5-step checkout

- Enabled and disabled automatic stock management

- Uninstalled and reinstalled module

 

From product page:

- Made sure the product has a weight and dimensions

- Left carrier set to blank since blank is supposed to mean user can choose any

 

From shipping carriers page:

- Edited USPS priority shipping to have a weight range of 0 to 5lbs

- Tried even adding a "root" category 

 

No luck.

Any ideas?  This is killing me.

I've made some progress with this if anyone cares to help.

 

I believe the UPS and USPS modules aren't quite compatible when you install them both.

 

What I just went through:

 

1.  Completely truncated all of the ps_carrier_xxx tables in the database.  The USPS module doesn't uninstall properly and had duplicate records in there.

2.  Installed only the USPS module.  Chose "variable", "non-machinable", and the other normal defaults there rather than gambling with rectangular/etc.

 

It worked!

 

3.  Switched back to one-page checkout mode

 

Still worked

 

4.  Installed the UPS module

 

No longer works, only the UPS module appears!  WTF !?!?!?  I took a look in the Shipping > Carriers menu, and all of the USPS modules were missing.  OK now I'm confused.

 

5.  Took a look at the ps_carrier table in the database, and noticed that all of the USPS rows are still in there, but for some reason a column called "deleted" is set to 1 on them.  I have no idea why, but can only suspect that somewhere during the UPS installation this happened. I manually edited those rows to 0.

 

Now, things seem to be working, and I can pick from both USPS and UPS on checkout.  It's 1:30am, so I haven't tested this any more thoroughly, but wanted to share to see if anyone has an idea on why this is happening.

 

I would be VERY nervous to put something like this into a production environment.
