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 ?

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 ?

Should you require login details please let me know.")* 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.
