PayPal gateway not working

-- HikaShop version -- : 6.1
-- Joomla version -- : 5.3.4
-- PHP version -- : 8.4

Hey,

I have an odd error on the site. PayPal does work but after payment it goes to an error page (See screenshots). There are no overrides and I have tested on the default template.

Also, sometimes, payment is taken, even though the message is "The payment request was refused by PayPal"

Can you please help me try to get to the bottom of this please?

Many thanks.

Hi,

For the "syntax error", please reproduce it with the "debug" setting of the Joomla configuration page turned on. It will display more information on the error and with it, we should be able to tell you what to do.

For the other one, please look for errors in the console of your browser while on that page. It should provide more information on the issue.

Today I am unable to process the form with the "please fill in all the fields..." comment.

See attacehd screenshot. I do have debug and error reporting maximum (I didn't see any errors). The Consol error is attached in the image. What can I try next please?

Hi,

The console indicates there is a PHP error.
You can see at the bottom left corner of your screenshot the text "SyntaxError: Unexpected token" which points at a PHP error, when it is expecting a JSON text to be returned by the server.
This is probably linked to the error you had in your second screenshot in your first message.
Are you not able to reproduce it with the "debug" setting of the Joomla configuration page activated ?
The extra details would allow us to tell you what to do.
Otherwise, PHP error log should also contain the full error message if you have access to it.

And if nothing is possible, please provide a backend access via our contact form so that we can directly reproduce the issue on your website and investigate deeper.
