 * Hi,
 * I am using version 1.4.3 and I noticed that when I installed Swift Performance
   Lite plugin that I couldn’t click on any settings. I looked at the Chrome console
   and there was a js error. Disabling the plugin allowed me to continue. Would 
   it be possible to fix this as I love the plugin and use it all the time.

 * Hi [@bharte](https://wordpress.org/support/users/bharte/)
 * My apologies for delayed reply.
 * Could you please provide more details?
 * We tried to reproduce the issue, but without any luck.
   Nevertheless we believe
   that the issue may be related to different plugin than Swift Performance Lite.
 * You can generate free sandbox site using this URL: [https://tastewp.org/plugins/swift-performance-lite/](https://tastewp.org/plugins/swift-performance-lite/)
 * It will create fresh WP Installation with SPL and our plugin installed, everything
   seem to work without issue.
 * Please specify on which WP page you noticed that error, was it within SPL settings
   or posts/pages menu?
 * Thank you!

 * Hi,
 * I have installed the Swift performance module. I didn’t install anything else
   or any content. As you will see the Swift settings buttons are unresponsive (
   wont update to enable/disable when you click) and there is a js error on the 
   page although it’s possible it is a different one this time.
   The symptoms of 
   not being able to click any setting buttons is the same as I had on my own site.
   Please let me know how you get on.

   Screenshot
   It’s possible on my own site I didn’t click auto config as my js is
   not minimised. Here I clicked auto config in swift and therefore js is minified
   by default. Possibly if it was reset and js was not minified then the same js
   error as on my site would appear.
