Regards, Patrick")* Hello, Your front-end template does not support the display of the call-stack. By switching to "protostar" (and with the debug mode), we can see more details of the issue. Code: implode(): Argument #2 ($array) must be of type ?array, string given /home/lorcestlor/v2/administrator/components/com_hikamarket/classes/category.php:532 Which allow us to fix the issue. You can re-download the HikaMarket 4.0 package to get the hotfix. Thank you for your report ! --- Jerome - Obsidev.com HikaMarket & HikaSerial developer / HikaShop core dev team.
