 * Hi [@fmsgroup](https://wordpress.org/support/users/fmsgroup/),
 * Could you enable the plugin itself, but then disable the optimizations in the
   plugin settings? This is the first setting in the plugin screen.
 * After you do this, I’m able to test the plugin from my side, without it showing
   for your visitors.

 * Any update?
 * Are there any option to exclude certain plugins or scripts when minifying js?
 * I find that this issue dissapear when “Load scripts asynchronously” is on, but
   this option make the site much slower because it makes third party scripts load
   first.
 * So im wondering if there as an option to exclude certain scripts
 * Regards,
