Fatal error: Call to a member function display() on null in checkout.php on line

Hi,

This would indicate that you're missing the file administrator/components/com_hikashop/types/default_registration_view.php or that the file administrator/components/com_hikashop/view/config/view.html.php doesn't contain the line:
'default_registration_view' => 'type.default_registration_view',
This shouldn't normally happen. So either the file was deleted or there was a problem during the transfer of the website to another location, or there are some permission issues on the folders and the update couldn't add or modify the files.

Please check that the files are there and that the code I'm talking about is there.
If not, check the permissions of the files and their folder and install again the HikaShop install package. It will overwrite the files and fix the issue.

Hi,

So, can you confirm that you have the file administrator/components/com_hikashop/types/default_registration_view.php and whether the file administrator/components/com_hikashop/view/config/view.html.php contain the line:

'default_registration_view' => 'type.default_registration_view',

Hi,

This is a file from HikaShop 3.2.0. In your first message, you said that you are using the 3.2.2.
So that would mean that this file wasn't updated because of permission issues as I excepted.
Then rename the folders administrator/components/com_hikashop/ and components/com_hikashop/ via FTP and then run the HikaShop install package again via the Jooml installer. That will add all the files with the same version and you won't have the problem anymore.
