Aggravating theme/image issue

There are a bunch of existing threads on this but they all seem to be many years old and seemed to concern old versions of wordpress.

I’ve got the homepage sorted out already http://www.michigangeneralcontractors.com/ logo, middle, and slideshow images all showing up fine just how i want

But on my newly created page http://www.michigangeneralcontractors.com/roofing it allows me to upload an image to my gallery, but when i click on insert, nothing happens…it just stays blank, no image is inserted

I’m having the same issues for another domain, same host…same theme http://www.llconstructiongroup.com/ everything works fine with the themes homepage settings, but new pages/posts…i can insert youtube video embeds, schema code and everything else just fine…it just wont let me insert images
