How to Check if WP Rocket is Caching Your Site

Issues like this are often related to one of the additional options in WP Rocket.
To identify which option causes the problem, proceed as follows:

  1. On the Media tab, uncheck LazyLoad
  2. On the File Optimization tab, uncheck each option, one at a time.
  3. Each time you deactivate an option, check your site in a private/incognito browser window where you're not logged in as a WordPress user.
  4. Reload the page a couple of times to make sure it's cached. When the issue resolves, you know it was caused by the last option you disabled.
  5. Once you know the option that causes it, consult this guide for possible fixes: Resolving Issues with File Optimization
