Joomla 4 upgrade is failing

-- url of the page with the problem -- : salsashoes.com.au
-- HikaShop version -- : 4
-- Joomla version -- : 3.8.13
-- PHP version -- : 7

Hi,
I tried to upgrade to new version of Joomla (latest stable version 4) but it seems not working. Please see photo attached for error and link address. (I had to restore my website to the previous version (using Akeeba backup) to keep it functional. Help Please?

Hi again,
To make it easy to see the error I have created a staging version of my website and error, please check the link:
staging1.salsashoes.com.au/ladies-shoes/salsa-latin.html

I have the same problem. I also posted it. Hope they can solve it. I played back my old version for now.

The same problem here.

Hi,

Sorry for that, it's a bug introduced yesterday following a hot fix for another issue. This was patched again just now. So please download again the install package on our website and install it on yours and it will work fine.

Hi nicolas,
It seems the latest version has resolved the main issue but I am still getting a warning message plus lost the two columns setup (I deleted and cleared all cache). An example on the warning can be found on:
staging1.salsashoes.com.au/men-shoes.html
Any suggestion?
Regards

Hi,

This comes from a view override of your template.
Rename the file /templates/gtishop/html/com_hikashop/product/listing_div.php in order to deactivate it and use the default view file of HikaShop and it will work properly.

Hi nicolas,
Many thanks. I disable the "Use bootstrap v2 design" under the "Legacy Settings" in HikaShop Configuration, it seems to have resolved the problem.
