Problem after migration and PHP update

-- HikaShop version -- : 4.7.1
-- HikaAuction version -- : 3.2.1
-- Joomla version -- : 4.2.7
-- PHP version -- : 8.1.
-- Browser(s) name and version -- : Chrome
-- Error-message(debug-mod must be tuned on) -- : Call to a member function getUsersWithMaxBid() on null

I just migrated my website to Joomla 4 and have set PHP to 8.1.

In the backend all goes well but on the frontend when I call one of the finished auctions I get an error.

Hope this can be solved. Should you require login details please let me know.

Hello,

Can you provide these elements in order to allow us to better understand the situation :
- Active the Joomla Debug and in the level maximum :

- Make a new screenshot that will show us everything about the current error.

Awaiting your elements to progress on your subject.
Regards

Hello Philip,
Hereby the screenshot of the errors.

Hi,

Thanks. That's a strange error.
I'm not able to reproduce it on PHP 8.1 and Joomla 4.
Also, I checked the code and as far as I can see, the only way to get that error is if the file administrator/components/com_hikaauction/classes/auction.php would be missing or empty or something like that.
Could you check on that ?
Could it be that the file was not transferred properly at some point while you migrated your website ?

Hi Nicolas,
Thank you for taking a look. The file administrator/components/com_hikaauction/classes/auction.php is present and not empty.
Please see attachment.
Kind regards,

Hi,

The file looks good and it's the same I have on my end.
So I'm not sure how it can work for me and not for you.
Could you provide a backend access (to be able to activate the debug mode), FTP access (to do some debugging in the code) and the URL of the page with the issue on the frontend, along with instructions (if necessary) to reproduce the error via our contact form ?

Hi Nicolas,
You've got mail. Thank you for your help.

Hi,

The issue comes from an override.
You have the file /templates/yootheme/html/com_hikaauction/administrator/classes/auction.override.php
This file tries to load the file administrator/templates/isis/html/com_hikaauction/administrator/classes/auction.override.php which doesn't exists on Joomla 4 since the backend template changed.
So it's a customization problem, not a problem in HikaAuction.
Delete the file /templates/yootheme/html/com_hikaauction/administrator/classes/auction.override.php and it will work normally. Now, this means that you had a class override so it also means that you'll lose the customization. You would have to get the file administrator/templates/isis/html/com_hikaauction/administrator/classes/auction.override.php from your old website on Joomla 3, to see what it had... Maybe you need to redo the override.

Hi Nicolas,
Thank you for research. Glad to know what the problem is. I will look into the overrides.
Kind regards,
Marloes
