Hi – thanks for the reply
I am inserting images: on sidebar and in the actual page. For the sidebar, I used either the Black Studio widget to upload the photo, or the image widget. To insert in the post, I use the “add media” button. Forgive me as I am not an expert of this by any means. When plugin is deactivated, all images are visible with no issues. Once activated, the images come and go leaving a blank white spot, which still hyperlinks.
Hope that helps. Thank you.
