I just updated to hikashop 4.0.1 but now I get 2x the same error message in the back end of hikashop.
Warning: implode(): Invalid arguments passed in /administrator/components/com_hikashop/classes/widget.php on line 711

Hello,

HikaShop 4.0.1 received some hot fixes for the widget part.
Would it be possible to know your build number version ?

Please note that warning are not errors ; they do not create direct issues and warning messages should not be displayed in a production environment (for various reasons, including security purpose).

Regards,

version: HikaShop Starter 4.0.1 [1811301551]

These messages are displayed in the production environment e.g. dashboard.

Hi,

What Jerome said meant that on a production environment, you should turn off the "error reporting" setting of the Joomla configuration and thus you should not see that warning.

Download again the install package on our website and install it on yours. That will add the patch for that warning.

The debug system was set to no when this occurred.

Hello,

Joomla debug mode is not the same thing that displaying PHP notices in the generated pages.
In Joomla you can see to override that PHP setting ; but best to let your web hosting dealing with that and not force the display of PHP messages, for your own safety.
Please don't hesitate to contact your web hosting for that and to perform some search on Internet to help you with the configuration of your Joomla website.

Regards,

Thanks. I see: global configuration - server - error reporting: now set to none. Now no messages anymore. Was set on system default. But in former versions this has never occurred.
