Hello Isaa,
Sorry for the problem with the preview area being completely blank when customizing your theme selected from the Inspirations. You classified this under “Working with Ninja Forms”, so we were a little confused as to which article or section of BoldGrid that you are referring to. Please provide the article that you are using for guidance so that we may update it if that is required. I did try to PREVIEW a theme selected in Inspirations and I am able to see the preview work. Can you also please verify the versions of the installed BoldGrid-related plugins? You can make sure you’re using the most updated version by going into the Plugins section and updating each plugin as needed. Please see How to Update BoldGrid for more information.
If you have any further questions or comments, please let us know.
Regards,
Arnel C.
