products no longer appear after an update

Hello,

That thread should help you :

Hello,

The issue is related to Joomla 3.8.9/3.8.10 ; and the thread is talking about patches which need to be applied in some views and in some views.
We release HikaShop 3.4.1 in order to provides theses patches and some time after, we release HikaShop 3.5.0 with the features that we were working on.

Now your issue is the same problem described in the pined thread ; so it is an issue with the modification of the Joomla core regarding how the "params" are handled.
You have to check that the patches listed in the thread I gave you, are right applied in your website.
Best is to use a FTP access to verify manually the files and see if the modifications are right there. You can also use your backend access to check if you have overrides or not, but for what you're describing, you already test to change the template (but checking the folders could be safer)

If the parameters are not read correctly in the view, there is no possibility for HikaShop to display the products, since it cannot access to the parameters and know what it need to display.

Hello,

You gave backend access ; but with these accesses we cannot check the FTP files.
Please perform theses checks and then we could start to investigate in our side.

Please understand that you are the only user who have the issue after the update ; so the only solution that we can think about right now is that you have some files which are not up to date.

Hi,

I'm not able to access your backend nor your FTP access:
monosnap.com/file/q0f3r3Ud6HY2Ey9v9NoF3ygURDesC0
monosnap.com/file/tzngoZ0aJaEDnDbI9t3mpEvOwgDMg4
It seems we're blocked or something as we can't even access the frontend.
Could you please check on that ?

Hi,

As expected, there was a template override for the file templates/YOUR_TEMPLATE/html/com_hikashop/category/listing.php on your website. I renamed the file and now I get the products on the link you gave:
monosnap.com/file/wTMnwvZ602fktvl4OWSOKoR2msqzEf
So the issue was exactly what was described by Jerome on the other thread. It's too bad you didn't check. You coudl have saved yourself 2 days of waiting.
