Hi Hikashop Team!

I am experiencing an error when I try to Delete or Refresh Items in the Cart, once Added.
I understand that my Hikashop Business is not that Latest Version but I am not ready to Upgrade this as it may cause other Issues.
I've tried the recommendations in other other Forum Topics such as deleting the Menu Items but I am not able to solve this issue.

Also tried switching to a Default Joomla Template, which makes no difference...

When I click on Delete or Refresh I get this error:
Error

Please complete the Name field

Please complete the Name Color field

Please enter a value for the field Name

Hikashop states to populate these fields but they are Populated...?

Hi,

I'm not sure what is the problem.
I would surely recommend updating, but I'm not sure it would help.
I do see several javascript errors in the console of the browser on the checkout.
These are caused by some optimization tool moving the javascript files and code in the header at the end of the body, resulting in the javascript directly in the middle of the body not finding what should be already loaded.
I would recommend disabling this so that the javascript is properly added to the head of the pages. That might be enough to fix the problem.
If not, the next step would be trying with the default template of Joomla, to see if it is linked to a view override, or some problem in the template, and if you have the problem even with the default template, then updating should be the solution.
The frontend of HikaShop on your website looks fairly normal so I don't expect much issue with the update of HikaShop. I think it will do more good than bad.

Hi Nicolas, thank you for the reply.
Are you able to tell which Component is messing with the Java Script?

I have tried a few and I am not able to uninstall all of them - So I think the best way forward is to delete the files and the database Tables of those components - no?

Don't stress about this - I have found the Plugin that is causing the issues!
