    I've been developing in Sitefinity for about 6 months now and suddenly I have encountered this error which I can not get around.  "No parameterless constructor defined for this object."

    I've turned on tracing by placing this in the web.config:
    <trace enabled="true" pageOutput="true" requestLimit="40" localOnly="false"/>

    But it will not trace.

    I've attempted to place breakpoints in the global.asax, masterpage, and numerous other locations but I still only get this error on any page I attempt to access and I cannot get any more information about this.

    I've included the following from the error log:

    Hello Joey,

    Form the error you are getting it looks like you have a custom module or provider where you do not have a parameterless constructor defined.
