I am able to add an image at it's original size to a page, but when adding anything else - like a thumbnail, expand button, description and then saving the entire page goes blank.
No text or image appears, even though the page has data on it. If I remove the formatting and just insert the image from the file gallery everything works fine.
I've been using the image icon on the edit page to choose the options from, so I know it's not an issue of having typed in something wrong.
Anyone else seen this - or have an idea how to fix it?
What I really want is a thumbnail at the right of the page with a caption, and an option to open the thumbnail full size.
