Hi,
If go in the HikaShop version, next to the version number, you can see the build number which starts with the date of the creation of the build and then the time (UTC-1).
On your website, I can see that you have the build 1705041726, so from the 4th of May. However, my previous message on this thread and the patch were done on the 5th of May. So it's normal that you still have the problem as the build you're using is older than when we added the patch to fix the issue.
Please download again the install package on our website, and make sure that you use that package and not another one and install it on your website and you should get the latest build with that patch. It should then work fine.
