Okay. I've combed the forums and I can't find anything that helps. Whenever I have shipping included in my shopping cart, the PayPal payment module won't complete the final step. I just get the same page every time I click the finish button.

1) I have double checked that the template will output errors and that other errors will display, so it's not an error thing. I have also enabled Joomla debug mode and it shows no errors.
2) I have tried with both the USPS and Manual shipping modules.
3) I removed the weight from my test product and turned OFF "force shipping if no weight" option and that brings me to the paypal checkout page, but doesn't allow any shipping.
4) If I leave no weight, and turn ON "force shipping if no weight", then it gets blocked on Finish again.
5) If I have shipping options turned ON and get to the final step, and THEN I go into the admin page and remote weight for the product and disable "force shipping", then the PayPal page DOES come up with the shipping included.

SOMETHING about having a shipping module enabled is breaking the final step in PayPal checkout... and that's the only payment option I need, so now I'm stuck.

It looks like if I remove the "Shipping" workflow item from the checkout process, it works fine. Go figure.

Sorry. I literally downloaded the install package the same day I made the post. I'll have to dig up the version number.

As noted in my follow-up, it appears that the shipping module settings aren't the issue. I can see the problem using usps and manual shipping. If shipping charges are in the cart, and a "shipping" view is in the checkout workflow, it gets stuck. Since it works fine without the shipping view in the workflow, I'd guess that the real bug is in the workflow engine and not the PayPal plugin.

I'll dig up some screenshots as soon as I can...
