What version of Safari are you using? Any version less than 10.0 is no longer supported by Apple and you should update. We cannot guarantee support for browsers that are no longer supported by their own vendors.
I have made a small change for some old versions of Safari, which might help you. If not, the only solution would be to try a newer browser version, or if you can't update because Apple no longer supports your OS, you can try a different browser such as Firefox or Chrome.
