Can the control navigation be turned on for the lighthouse theme. The option is enabled. I thought by updating the jquery.nivo.slider.js file controlNavEl: true would enable the option.
The issue has been fixed now for version 3.5. If you are using this version you can update your plugin and this functionality will work. Here is a video on how to update a Nop Templates Theme. If you are using older versions of nopCommerce I will provide you with the css code that will resolve this issue.
Would it be possible for you to submit a ticket about this issue from My Account / New Ticket. This way it would be easier for me to send you the file you need to replace, because in the forums I'm not able to send files.
