Hey,
Thanks for reaching out to us! It appears that there is some conflicting Featured Post widget, shortcode within a text widget or something creating extra content before the content of our plugin starts https://cloudup.com/cxSUpjAZnaX.
When customizing, are you adding the image using “the_post_thumbnail()”? If so, you can:
- Create a new thumbnail size using “add_image_size”
- regenerate all your thumbnails using something like https://wordpress.org/plugins/regenerate-thumbnails/
- When adding the image, use “the_post_thumbnail( ‘your_new_image_size’)”
Let me know if this helps.
Thanks!
