    We are running the latest Telerik controls (2018).  I have a small report that works fine in the dev environment but when I push to the server and run the report, it says 'Generating Report' for a sec then I get a blank page.  It works fine in Chrome (but most users use IE)

    VS 2017

    any help is greatly appreciated.

    Hello Mark,

    If I understood correctly, upon deployment on a different from your local environment, the ReportViewer is not displaying in the IE browser, while it works correctly with the Chrome browser.

    When the viewer works properly in one browser but fails in another, it is most probably a browser compatibility issue. So, I suggest you to check if the IE is working on Enterprise mode or Compatibility View mode. Note that Telerik Reporting HTML5-based viewers do not support Internet Explorer 8 (i.e. Enterprise mode). The minimum required versions are listed in Browser support help article.
    If so, switch to Native view by unchecking the Enterprise mode, or if in Compatibility View mode by going to IE Settings -> Compatibility View Settings -> (uncheck) Display intranet sites in Compatibility View.

    Telerik Reporting HTML5 Report Viewer depends on the Promise object and will not load successfully if not available, as explained in the Requirements help article. Please, check if there are any errors in the browser console (F12). If there is an error 'Promise' is undefined' would indicate that the browser does not support Promises. If so, please check the Error: 'Promise' is undefined KB article.

    If the above does not solve the problem, we would need additional information to try locating the problem and give you specific suggestions, so please open a new support ticket containing the following: 
    - the project, so we can investigate locally;
    - a Fiddler log file of the requests and responses (you can check how to generate a .SAZ file)

    Progress Telerik
