 * Hello. Our error reporting is catching a lot of console errors from this plugin…
 * `null is not an object (evaluating 'commentForm.querySelector("#author").addEventListener')`
   `
   commentForm.querySelector(...) is null` `Cannot read property 'querySelector'
   of null` `Cannot read property 'addEventListener' of null` `null is not an object(
   evaluating 'document.getElementById("commentform").querySelector')`
 * Various places, but for sure on WooCommerce products and blog posts
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fjavascript-errors-50%2F%3Foutput_format%3Dmd&locale=en_US)

 * Can you advise what browser? I have just tested WooCommerce + Chrome and see 
   no console errors?
 * Also are you using any caching / optimisation plugin that is doing things to 
   Javascript at all?

 * OK I have got it -it occurs when a user is logged in – the comment form exists
   but there is no author box.
 * I’ll add an extra check in the next release.
