ERROR at checkout: 0 Class "JArrayHelper" not found

-- HikaShop version -- : 4.7.5

-- PHP version -- : 8.0.30
-- Browser(s) name and version -- : Chrome Version 115.0.5790.170 (Official Build) (x86_64) (also happens with all other browsers tried)
-- Error-message(debug-mod must be tuned on) -- : 0 Class "JArrayHelper" not found

Migrating using MigrateMe4

With your help i was able to update the public store, a near copy, to J4 after removing email customizations. I did so on this site as well but get this error at final checkout

0 Class "JArrayHelper" not found

That appears in Chrome browser tab, otherwise i see my 404 page.

Jooomla 4.3.3
PHP 8.0.30
Hikashop 4.7.5
Hikamarket 4.1.1

I read that OSMap could cause issues, so I've uninstalled all pieces.

I uninstalled the XMap plug as well

What have i missed??? Thanks...

Hi,

Hard to say as that's the abreviated message, not the full error message.
Please activate the "debug" setting of the Joomla configuration and reproduce the error. You'll get the complete error message which will allow us to understand what's going on and tell you what to do.

Here is the full info

Hello,

There is no more "JArrayHelper" in the plugin since October 2018 and the release of HikaMarket 3.0.0
All "JArrayHelper" have been replaced by internal functions from the HikaShop/HikaMarket cores.
www.hikashop.com/support/documentation/1...arket-changelog.html

But the plugin "Shipping Fee Per Vendor" is not part of HikaMarket since it's a custom plugin ; which has been updated in 2018 like the rest of the HikaMarket eco-system.
Please replace the By
Regards,
