Extension MultiSafePay gives 500 error

-- url of the page with the problem -- : swann.eu
-- HikaShop version -- : 6.3.0
-- Joomla version -- : 6.0.3
-- PHP version -- : 8.4

Hi,
Is there anything that could cause sudden 500 errors when using this plugin:
www.hikashop.com/support/documentation/4...ltisafepay-form.html ?

Maybe not compatible with Joomla 6?

It is not used very often but looks very recent that this happend.

Hi,

That or PHP 8.4, or some specific combination of things.
Could you reproduce the issue after activating the debug system setting of the Joomla configuration page ?
That should hopefully display an error message with more information on the issue.

Hi, I got some error messages that appear in the console when trying to pay. I hope they are helpfull :

Warning: Undefined array key 0 in /home/www/public_html/administrator/components/com_hikashop/classes/currency.php on line 1126

Warning: Attempt to read property "currency_percent_fee" on null in /home/www/public_html/administrator/components/com_hikashop/classes/currency.php on line 1131

Hi, is the information that I provided of any use? Happy to provide anything else if you need it.

Hi,

Yes, sorry. The plugin is not developed on our end. Normally, you're supposed to directly contact the developer. I've discussed the problem with the developer and he said he would look into it but didn't had the time yet.
It's an incompatibility between the version of a lib included in the plugin and the same lib from elsewhere. So he needs to look into it for a suitable solution.

Hi,
Do you know if there is any update on this?
I tried mailing the developer but I have not received any reply yet.

Hi,

I've contacted the developer on my end and he told me that he didn't forget about you and he'll look into it as soon as possible.

Ok, good to hear. Thanks for the update.
