    I am posting this solution in case someone else encounters this problem.

    I was receiving the error "Spell Check Handler Server Error:500  Invalid length for a Base-64 char array." whenever the editor spell check button was clicked.

    The problem turned out to this line in Web.config:
    <globalization requestEncoding="utf-8" responseEncoding="ascii" />

    This was left over from the Netscape 4.x days.  NS4 used to display text as squares afer a window was moved over the browser, if UTF-8 enconding was used.

    Changing the line to this solved the problem:
    <globalization requestEncoding="utf-8" responseEncoding="utf-8" />

    Hi Gavin,

    Thank you very much for sharing your solution! I updated your Telerik points for that.

    I would like to share among our DNN users this KB article:

    RadSpell "Prometheus" for DNN FormatException: Invalid length for a Base-64 char array.
