You created a lot of reports with crystal reports and everything was fine until you uploaded online. You get no error just a blank page with nothing on it. What has gone wrong, "Is it because there are no records in table", you ask yourself.
Well I myself got stuck with this error few days ago, so i created a blank report with just a custom static text in it, but nothing showed up. After a lot of searching I found out that it was because of a missing folder named "aspnet_client" which must be present in order for crystal reports to work properly.
So I copied this folder from c:/inetpub/wwwroot/aspnet_client into my website and voilà it worked.
and for dot net framework 4.6 just copy existing framework folder in aspnet_client\system_web folder and the rename it to 4_81 or what ever version is installed on your system and your are done
