Did you try some troubleshooting first? Check to see if it works fine in a default theme. If it still does not work in a default theme, try to see if a plugin could be causing the issue also by doing the listed steps for troubleshooting a plugin issue.

Plugin/Theme updates could cause an issue to pop up without it previously being there before.
