I have a rather strange problem that I can't find an answer to on the internet. I have an installation of Reporting Services 2012 in which the reports after running do not show anything except the top bar with the controls to change the page, export, etc.
Although the reports do not show anything, if I select to export to any format, the report is exported correctly with all the content and data that it should display on the screen.
The reports have few parameters which are never associated with a list of possible values and have a single default value for all parameters.
Any idea what might be happening? The only thing I can think of is to reinstall the reporting service.
From the report editor in Visual Studio the reports work fine.
The problem disappeared after reinstalling SSRS
