 * Hello!
 * I’ve spent a lot of time refining my asset optimisation in Hummingbird and everything
   seems to be working fine. However, when using the Inspecter on Google Chrome 
   it says that I have 9 Javascript errors on the homepage (as well as many other
   pages of course). Despite the website working completely fine, should I be concerned?
   Do errors slow down the page load-speeds? These 9 scripts in particular that 
   I speak of are all deferred scripts.
 * Thanks,
    – D

 * Hi [@dazzerr](https://wordpress.org/support/users/dazzerr/),
 * I recommend you resolve the errors, because that can cause certain parts of your
   website to not function as expected.
 * Best regards,
    Anton

 * Thanks for your swift reply Anton! I’ve tried a few different combinations and
   they don’t seem to clear up the errors list too much. They all seem to be “Uncaught
   TypeErrors”, whatever that means. I’ll have to do a little more research into
   the errors, but I assume it might not be much of a problem.
 * Thanks Anton,

 * Hello [@dazzerr](https://wordpress.org/support/users/dazzerr/)
 * Hope you’re doing well!
 * To resolve the JS error in the developer console, please create a staging site
   and run a test for a conflict with a plugin.
 * Deactivate all the plugins and see if the JS errors are there. You can just change
   your theme to see if the errors still there. Start activating one plugin at a
   time while checking the console for more errors. Once the errors will start showing
   up, the last plugin may be conflicting with another.
 * Hope this helps!
 * Cheers,
    Nastia
