Hi,
Thanks for the backend access but as you know, HikaMarket is a front-end component.
The tip that I can currently give you is to take a look at your browser javascript console.
There you will be able to see the javascript errors and see the error message.
Like in the HikaShop product listing page:
shortcodes.js:55 Uncaught TypeError: $(...).carousel is not a function
Or another visible in HikaMarket pages
shortcodes.js:93 Uncaught TypeError: $(...).swipe is not a function
As you will be able to see ; the javascript errors are not in HikaShop or HikaMarket but in the javascript file "shortcodes.js" which is a file of the system plugin "ytshortcodes".
Please contact the support of that plugin in order to get more details and have a solution to fix your issue.
Regards,
