Migration to Joomla 4 issue

Hi,

I don't know.
I checked your website, and when I access a page under the "products" menu, it says "component non found".
I suppose that's because you deactivated HikaShop.
What error do you get on that "blank frontend page" ? Is it totally blank ? If you have an error message can you provide it ?

PS: Note that since a few days, I can see that you're contacting us with issues and questions on several different websites. Please understand that the support included in your HikaShop Business subscription is for only one website. I'm feeling you're abusing our kindness by expecting support for many websites for the same HikaShop Business subscription.
If you need support for many websites, I would recommend you to switch to HikaShop Multisites:
www.hikashop.com/extensions/hika-multisites.html
This is a HikaShop Business with support included for as many websites as you want. It seems that this is what you should be purchasing to be in line with how you're using your HikaShop. Otherwise, we expect you to purchase one HikaShop Business subscription for each website where you need support on HikaShop Business.

Hi,

From what I can see there, it looks like a htaccess issue:

The HTTPS version of the website is redirecting you to the HTTP version and vice-versa.
This normally indicates that the htaccess has been changed in an incorrect way.
I'm not sure why publishing or unpublishing HikaShop would change that though.
