ISSUE: Shop the Post affiliate widget doesn't have a white background
This Help Desk article assists you in troubleshooting when an LTK Shop the Post widget is properly set in a theme widget area, but is appearing without a white background. Here's an example of this issue:
This happens when an LTK Shop the Post widget is placed into a WordPress Custom HTML widget. Within our themes, Custom HTML widgets are coded to have no background, for maximum flexibility based on the types of code or scripts customers may place into them.
To solve for this issue, instead of pasting your LTK shortcode into a Custom HTML widget, simply paste the shortcode into a Text widget, then add it to the same widget area. It should work exactly the same!
