 * Hi Frank. Turns out, the broken form (generated by Calculated Fields Form plugin)
   might be an issue with Autoptimize after all.
 * Here’s what their team found (screenshots included): [http://wordpress.org/support/topic/compatibility-issues-with-autoptimize?replies=12#post-5938259](http://wordpress.org/support/topic/compatibility-issues-with-autoptimize?replies=12#post-5938259)

 * Hi barefoot bookworm;
    In that case you could either excluded the isotope js-
   file from being optimized or you could enable “try/catch”-wrapping to stop the
   error in the optimized Isotope-js from impacting your other JS.
 * Hope this helps,
    frank

 * At the risk of sounding stupid…what is an isotope js file? (I tried try-catch,
   it didn’t work.)

 * [isotope is a js component to “filter and sort magical layouts”](http://isotope.metafizzy.co/),
   which one of your plugins (or your theme) is using. Easiest solution is to disable
   JS optimization to find how isotope is loaded and then use that string (possibly
   isotope.pkgd.min.js) to exclude it from being optimized. You might have to “force
   JS in head” and/ or exclude jquery (on which isotope can depend) as well.
