Image Not Showing up

Hello,

I have an image saved in my Primary Sidebar Widget. It is the “continue” button found after the quote tool. You can see it here, https://telsolutions.com/.

On any other page, the “continue” button image is not showing up.
You can see that here, https://telsolutions.com/broadview-teams-with-rca/

Up until yesterday the image was showing up. Yesterday, I made my contact page end in “/contact” instead of a number. I also added the two posts.
That is when the image stopped appearing.

Thank you for your help,

Mark
