If some of the features of a webpage don’t work, you may have turned off some utilities that help Safari handle special content on webpages.
Open Safari if it is not already open.
Choose Safari > Preferences, and then click Security.
Make sure these checkboxes are selected: Enable plug-ins, Enable Java, and Enable JavaScript.
Make sure this checkbox is not selected: “Block pop-up windows.”
If the steps above don’t help, you may need a plug-in application, which is a small program that assists Safari and adds to its capabilities.
You can also choose Safari > “Report Bugs to Apple” to report the problem.
