The warning you’re seeing likely arises because caching rules defined for the browser are not correctly reflected in the .htaccess file, which impacts the headers associated with static assets.
This issue typically occurs when some static assets (such as images, scripts, or stylesheets) lack optimal caching headers, meaning the headers aren’t set to instruct the browser to cache these assets efficiently. Without these headers, the browser cannot cache files as expected, leading to repetitive requests and a resulting performance warning.
To resolve this, a thorough investigation is needed to identify which headers are not being applied correctly. It may involve reviewing the .htaccess file or server configuration to ensure that the appropriate cache-control headers (like Cache-Control or Expires) are set for each type of static asset. Optimizing these headers will help ensure that assets are cached effectively, improving load times and reducing server requests.
