Hello,
We have a problem with a SharePoint 2010 Site, this site is suddenly throwing an error in the morning between 7:30 - 8:00 Am
and that error disappear also after that without anybody interaction and the site will get back to be working normally .
this is strange, I have worked on many SharePoint 2010 sites before and never face this issue .
the error is : object reference not set to an instance of objects .
