Here’s the page on my website:
Please take a look at this: https://codecanyon.net/item/essential-grid-wordpress-plugin/7563340/comments?page=23#comment_7009903
Basically, “in the SEO/LINK Tab in the Skin editor you can define the target of the link. Please set there to “_blank” and it will open in a new window.”
For any link to open in a new tab it needs a " target = ‘_blank’ " parameter. In Essential grid plugin use the SEO/LINK Tab in the Skin editor to define the target as ‘_blank’.
You can contact me here if you have any trouble finding it.
What system are you using ?
