I have been using the Volunteer Job Listing tool that was made for my organization in our Salesforce build with different campaigns for months but all of a sudden the sign up button has stopped working. Volunteers are no longer able to sign up for a job because the button is no longer click-able even though it used to open up a pop-up inviting them to fill out their personal information. We depend a lot on volunteer sign-up so this issue is critical for my organization. Here is where the object is hosted in an iframe our website: http://kidscodejeunesse.org/volunteer.html
