# Render Blocking Request: Unknown File

 * Page Speed Insights showed this file at the top of the render blocking requests
   list at 66 KiB. I have no idea what it is and would like to delete it. Contacted
   Divi support and all they said was it would be risky to delete it and gave me
   some optimization tips. Does anyone know anything about this file? Thank you.

 * Since you are using the commercial theme Divi, we [can’t really help you here in the forum](https://wordpress.org/support/guidelines/#do-not-post-about-commercial-products).
   What exactly did their support team advise you to do, and have you already followed
   their advice?
 * I took a look myself and don’t suspect a problem with blocked requests, but rather
   with a JavaScript event that loads the content. When you open the page in a new
   browser window, hover your mouse over your browser tab and don’t move it. You’ll
   notice that nothing happens. Nothing at all. You can wait two minutes – nothing
   happens. Only when you move the mouse into the website area does it load the 
   content to be displayed.
 * This means that you have some JavaScript in your website that is causing this.
   As a first step, I would recommend deactivating your optimization plugin WP Rocket
   to rule this out as the cause.

 * I understand your position and appreciate you taking a look and replying. They
   advised: disable critical css setting, if I keep it enabled increase the threshold
   height in the performance settings, set explicit dimensions for images and videos
   to prevent unexpected shifts during loading, reserve space for layout elements
   by setting min-height values for sections that might cause CLS, clear all caches.
   I’ve followed up on the recommendations—still working on the images. That large
   file still shows as a render blocking request in PageSpeed.
 * The JavaScript event you mentioned is interesting. I’ll dig into it and WP Rocket’s
   potential role. I’m very curious.
 * Again, thank you for your consideration and time.

 * Regarding the blocking file, I would recommend contacting WP Rocket support: 
   [https://wp-rocket.me/support/](https://wp-rocket.me/support/) – since this is
   also a commercial product, we cannot provide any further information here in 
   the forum.

 * I’ll do it. Once again, thank you.
