My blog, smicks.wordpress.com has a "Gallery" page (I'm not sure what sets such a page apart from any other page) which consists of a single, large post containing links to some 775 images and videos. There is also text interspersed with these images to act as subdividers and captions. Most of the images and videos were uploaded to the wordpress site and appear in the Media bucket as "attached" to the gallery page. Other content is stored at other sites. Everything looked good last time I checked some months ago, but now none of the content shows--no images, no links, no text. Only the few comments I have received are visible on that page. When I go to edit the page, the HTML content is all there, and at a glance all looks correct.
What has happened, and how do I fix this?
The blog I need help with is smicks.wordpress.com.
