Hello,

I have no idea what that error is about. Did you change the `index_page` or any other config that results in change of urls?

Please share the installation link with admin login details in private reply so that I can have a look.

Thank you

Hello, I uninstalled the files and reinstalled, everything went back to normal

I noticed that when changing the currency code of my country BRL to (R$) the error reappears

Hello,

There shouldn't be any issue with currency prefix as it is just for display. Please let me know your installation link with admin account details to check.

Thank you

Hello,

You are talking about online payment? Stripe and PayPal required ISO Currency prefix that should be 3 chars like USD, MYR, INR and BRL. If you want online payment, then please use the standard currency prefix of BRL.

Thank you
