Known issues & workarounds

VWO flickering issues

A few users have encountered problems while integrating VWO with CookieHub, which results in a momentary white page display after all elements have loaded and rendered in the browser. To prevent this issue, you can resolve it by incorporating the following CSS code into your website, ensuring that VWO cannot modify the opacity of the body element:

body {
  opacity: 1 !important;
  filter: none !important;

WP Rocket

WP Rocket caching can lead to problems with the CookieHub JavaScript file, such as delayed initialization, rendering the automatic cookie blocker ineffective. To resolve this, it's necessary to exclude CookieHub from WP Rocket.

You can find detailed instructions on how to do this in the following link: Exclude files from Load JavaScript Deferred (opens in a new tab)
