 * Hi,
 * Recently I started using Flying Scripts for a bunch of client and personal websites
   hosted with SiteGround. All these websites use the SG Optimizer plugin, with 
   minor differences in plugin configuration.
 * However one issue is consistent: the plugin Flying Scripts doesn’t work too well.
   
   It works the first couple of hours, but then your caching somehow doesn’t implement
   their lazy loading of scripts.
 * It is weird that it works for the first couple of hours, and then it simply stops.
 * Is there a chance that you could look into it?
   Thank you.

 * Hello [@ilovewpcom](https://wordpress.org/support/users/ilovewpcom/) ,
 * The Flying Scripts plugin provides a JavaScript optimization feature in the form
   of delaying specific JS scripts. The Speed Optimizer plugin also provides various
   JS optimization features and I’d recommend excluding the problematic JS scripts
   from one of both plugins in order to avoid duplicating the optimization features
   applied to these scripts.
 * You can find more information on how to exclude JS scripts from the Speed Optimizer’s
   features here:

 * In case the problem persists, we recommend submitting a support request through
   your SiteGround account. Our Technical Support team will be able to review your
   case and provide further information and assistance.

 * [@svetoslavvasev](https://wordpress.org/support/users/svetoslavvasev/): I already
   tried all that. I even tried disabling all JavaScript related optimization actions
   from SG Optimizer. And that doesn’t help.
 * But OK, I will try filing a support ticket via my SG account, thank you.
