Today when I opened up my SharePoint Site Collection, I found that alot of things are missing in the page, and the document library is not functioning
Normally the page should have functions such as project summary timeline, Newsfeed, Document display and options, also, on the top of the page, the setting options and links to OneDrive, Newsfeed, and Sites are missing as well.
How should I deal with this. BTW the central admin looks fine, but when i click on the Newsfeed, Onedrive or Sites, the page is just empty
What should I do here
