Hello, I have a store that is in the testing phase. I installed HikaShop and the Correios (Brazil) shipping plugin. I registered a product and a customer for testing. At first it worked perfectly, but after some changes in the HikaShop settings when making new tests the method of sending the Post Office did not appear anymore. Withdrawal methods appear normally. I did all the recommended tests on the related forum topics and it didn't work. Can someone help me?

P.S .: Sorry for my English, I'm using Google Translate.

Hi,

I checked the link you provided but I couldn't find anywhere to access your shop.
So I couldn't check on the situation.
It would be great if you could provide a link to a product, a screenshot of the settings of that product, and a screenshot of the settings of your correios shipping method.

Hello, as I had previously informed the store is in the testing / construction phase, for this reason you were unable to view the store and the product. I will enable the store and the product so that you can verify the problem.

Link to the store: rollover.com.br/index.php/loja

Hello,

Did you process the FAQ check, here ?
Plus, can you provide references to allow us to process some tests (by access on your checkout) we tried to create a customer account but some administrative references are missing.

Note : To provide these elements use our Contact us form, and don't forget to add some Url link to this topic in your message.

Awaiting your returns to progress on your subject.
Regards

Hi!

Yes, I processed the FAQ checks. The post office plugin and the shipping methods created with it worked for a while, but this week when doing new tests they stopped working. By chance, the customer account you created is this:



If so, I can give administrator permissions to that account so they can check the website's backend.

Very grateful for the attention!

Hello,

Sorry but can you double check your backend access references because for a reason or another the access isn't granted.
Regards

Hi!

Sorry, back-end access references have been granted.

Thank you

Hello,

we have check your relative configuration without be able to find the root issue... Maybe if you list HikaShop Configuration change you mean by this sentence :
"but after some changes in the HikaShop settings" maybe we can progress on your subject.
Other point, it seems that the plugin have to communicate with Correios servers, maybe Correios have changed his communication standards ?...
Contact them or search for clues on this side may be useful.

Awaiting news from you to understand better your context.
Regards

Hello,

I managed to solve the problem! Unfortunately I didn't find where the error was, I restored a backup before the error and everything went back to normal.

Thank you very much for your attention!
