Hi @gordon,
Yes, white space displayed in the page is where the blogs are displayed. The white space is there because of following reasons:
1. By default, the title for aside post format are hidden
2. The option you’ve chosen for the layout in “Customize=> Theme Options=> Layout Options=> Archive Content Layout” is Show Full Content (No Featured Image) and you’ve also checked “Check to hide excerpt/content on archive pages” box.
So different solutions would be following.
1. Change the post format to standard format.
2. Go to “Customize=> Theme Options=> Layout Options” either change “Archive Content Layout” to other options than Show Full Content (No Featured Image) or uncheck “Check to hide excerpt/content on archive pages” box.
If you don’t want the blogs content, let me know, I’ll provide Custom CSS.
Regards,
Mahesh
