There a multitude of reasons you can get blank pages. The first suggestion is right click on the report in solution explorer and select View Code from the dropdown. Use Ctrl + F to find "/Body" tag and make sure you set the width to 1In. Do the same if "TablixOuter" is in the report when you use CTRL + F (some reports don't have TablixOuter but all have /Body). Then hit Ctrl + S to save. DO NOT go back to the report design view. Deploy it and then try running the report. Please let me know if this does not solve your issue. I have been writing SSRS reports for 8 Years and have many other solutions to try.
