Edit This Page-Blocked

Happy Friday! I was in the middle of editing one of my Community sites, and when I go back into "Edit The Page" the drop down box is black. Please see screenshot attached. Nothing is appearing at all and I am unable to click into anything on the site to edit. I'm thinking something happened within the HTML widget I was editing, but I was never blocked out of going right back into "Edit this page" to adjust. Has anyone experienced this before and know how I can get back into editing this site? Thank you very much in advance for your assistance.
