Tab bar in personal page doesn't work.

When user click one tab in tab bar on his/her own personal page, it always displays the content of the tab "Contribution". This bug doesn't occur on every personal page.

On my personal page , this bug doesn't occur. When I click certain tab, corresponding content would be displayed. Everything works well. But on some others' page, it occurs.

My system information:

OS: MacOSX 10.13.1

Web browser: Chrome

For instance, on the personal page of @victory622, no matter which tab you choose in tab bar, it always displays the content of the tab "Contribution".

To demonstrate these two bugs well, I made the following video:
