    I'm just adding this post for others that might encounter the same issue in DNN.
    I have had issues on a DNN 9 site with adding modules in some circumstances.
    The issue was that after clicking the "Add Module" icon and selecting a module, I could not frag the module to the right Pane.
    Visually after selecting the module, I either saw an empty  square with a dashed / dotted border or
    a weird, half transparent preview of the placed module.
    But no way to drag the module.
    In the browser console you might see a Javascript error on $newModule.offset().

    Uncaught TypeError: $newModule.offset() is undefined

    I had the issue only on specific pages and found out it was caused by an HTML error (an extra < / div>) in the module that was already on the page.
    After I fixed the HTML error, placing modules worked correctly again.
    I did some tests and not all HTML errors seem to cause this issue.
    Also, an HTML error in your Theme might trigger the same issue.
