2.0.3. javascript error

Have 2.0.3 running on windows server. Created a form with a date field. But when you click on the calendar icon nothing happens and you get a script error icon in the bottom of the browser.

Found an old post that said to change the js_compression to flalse in the config.local.php. But this was for 1.3.5. Ours is set to false. Should I try changing it to true?
