Safari/ Instagram problem: Blank White Page

Does anyone have problem with Safari loading Instagram? Other browsers are doing ok but only Safari will not display Instagram and other websites. It won't even display the login portal for Apple Community. Safari's blank page issue has been affecting some users since 2010. I'm pretty sure it's Safari but I won't be too surprised if it's also an issue coming from Instagram. Is there a way to troubleshoot and fix this problem. I've been trying to ignore this problem since I use Chrome as my default browser. But I think it's time to get rid of this pesky nuisance. Your suggestions and feedbacks will be greatly appreciated.
