[SOLVED] - "PayPal Payments Standard" extension error after upgrading to OC 3.0.3.2

I currently upgraded to Version 3.0.3.2, but now the "PayPal Payments Standard" extension is giving me errors.

Everything looks normal when checking out, but at the last step of completing checkout, it gives this error message:

Things don't appear to be working at the moment. Please try again later.

Everything was working just fine before upgrading to OC 3, I'm not sure what I did wrong. I spent the whole night trying to figure it out and I just now realized the sun came up. Any one has any idea whats wrong?

Use the debug mode in your paypal standard extension payment module from the OC admin. Then, put your store under maintenance mode and see what the logs provides on the back-end for those errors.

I turned on debug mode and checked the error log, but there nothing there. I updated my first post with a screenshot of the error message i get from paypal.

I'm not sure if this will help, but notice the AMOUNT_ERROR in the URL

Well, error says for itself: amount error.

Yes, but where is it coming from? How do I fix it?

There's no generic solution for this issue, you need to debug it or hire someone to do this for you.

Understood, thanks for your quick response though.

I'm not 100% sure, but if anyone else is having the same issue, i think it was because my server didn't have "mCrypt" installed.

I don't want to go in to details, but the database wasn't restoring via ACP nor was it working via phpMyAdmin (said missing tables) *shrug*
I just accept the fact that I lost everything and decided to just start over again. After making an attempt to do a fresh install, it said one of the requirement was mCrypt. It's too late for me to check now, but I think that might had been what was causing the problem.

I am also have this same issue with the error after upgrading to Version 3.0.3.2:
https://www.sandbox.paypal.com/webapps/ ... b7c14dd4f2 >>> code=AMOUNT_ERROR
Things don't appear to be working at the moment. Please try again later.

I set Total = 0 so that any amount will trigger PayPal. When I change Total = 0.01 or Total = 1.00, the PayPal option disappears in checkout and I get:
Warning: No Payment options are available. Please contact us for assistance!

mCrypt appears to come from the server and I'm running ea-php73. I don't see any option for enabling mCrypt in PHP INI.

Any advice?

You could try this system/library/encryption.php file, it's the only one, still
containing some routine for the outdated mcrypt_encrypt standard, and
it should work on all OC Versions.
Good Luck!

Thanks! I renamed my old encryption.php file to encryption-old.php and created a new encryption.php file with the above code. However, it didn't appear to make a difference. I've also contacted PayPal and they're also helping me to resolve this issue.

@FrankR: Did you get a solution from PayPal?
I tried the suggested encryption.php but it did not fix the issue.
I am on PHP 7.2 and mCrypt is enabled (I checked with phpinfo).

PayPal did try to resolve this issue but we could not get it to work so I gave up on PayPal Payments Standard and tried PayPal Express Checkout. PEC did appear to work but the module broke my store because it would not let me access orders placed through it, which I could only access when I disabled the PEC module. It also did not include shipping so I had to send my customers a follow-up invoice via PayPal for freight.

I gave the PayPal Commerce Platform integration a try and it seems to be working. However, checkout doesn't work now because, although the shopping cart contents correctly appear, the order total does not.

So ... still not able to accept payments yet directly through OpenCart but at least PCPI doesn't appear to have broken my store so far.

To followup on this topic, I have PayPal Commerce Platform as my payment module and it seems to be working fine. My store was broken until recently because I was using the OC USPS extension. After switching to weight-based shipping, my store is back in operation again.

You will need to provide more information than that. What version of OpenCart? What version of PHP? What issue you were trying to solve? In what context you see that error?
