Hello,
not sure if this issue already came up here, but I noticed that the product slider was broken after updating Royal to version 4.7.1. I then found out that this was caused by a spelling mistake in product-image.php:
Line 31: $slider = $etheme_global[‘sliders’];
“Sliders” doesnt exist. So I changed it to
Line 31: $slider = $etheme_global[‘slider’];
and the bug is fixed. Just wanted to let you know if someone else is experiencing this problem and in order to fix it in the next update.
