Help! Cart is giving out free shipping!

[scythe000]

I upgraded to 3.0.19 from 3.0.15.

I thought all was well, until i staretd getting the 'failed to add package' error. I made sure there were no zero weights.

I tried the fix here: http://forums.cubecart.com/index.php?showt...mp;#entry165802 which did nothing.

I did this: http://forums.cubecart.com/index.php?showt...rt=#entry165802 and it was working. But today, I started getting orders with 0.00 for shipping! Help!

I also tried re-uploading the 3.0.19 files, and I'm getting this:

EDIT:

Ok, I reuploaded the original files and applied this fix to /modules/shipping/usps/calc.php:

Find:

case "Parcel":

Replace with:

case "ParcelM":

Shipping seems to be working ok. But for international, I still see about 12 different options, some of which are invalid. How do I remove the invalid entries?



EDIT2:



Ok, found a fix here: 

if($sum>0){

to

if(($sum>0) && (($api=="RateV2") || ($key=="Priority Mail International"))){

However, this breaks domestic shipping for me. You can see from the two phps attached, one works for international, but not domestic, and the other works for domestic, but has a zillion options ofr international.

This is my final problem, I'd be really happy if someone could help with this!
