My shop worked perfectly, but when updating from 2.7.2 to 2.8.3 (with all steps) I have 2 problems.
1. In the backend all products are disappeared (but they are visible in the front end).
The error that appears:
Warning: Invalid argument supplied for foreach() in /sitename/public_html/administrator/components/com_jshopping/views/product_list/tmpl/default.php on line 100
2. In the frontend at step 3 (payment) this error appears:
Warning: Invalid argument supplied for foreach() in /sitename/public_html/components/com_jshopping/controllers/checkout.php on line 218
You can not click "next".
Here you can test the shop:
I hope you can help me. Thanks!
