Error:

Unable to create or access workbook cache at C:\WINDOWS\TEMP\Excel Server\FileCache\SharedServices1-1078443246\Ranges. Excel Services is unable to function without a workbook cache.

(you can see this error in Event viewer)

Reason:

Unknowingly you may have deleted the above mentioned folders. So, Excel services is not able to save the temporary files under the "Ranges" folder.

Solution:

Login inside the SharePoint server and create the "Ranges" folder as per the above mentioned folder structure. If you are not able to see the "Excel Server" folder inside "C:\Windows\Temp" folder, just create it manually.
