Question2Answer script does not cache the CSS, browser does. In order to clear it, you need to add versioning into the CSS.

  1. You need to edit the following file; root/qa-include/qa-theme-base.php line 316 (v.1.7.2). 
  2. Comment the first code and add the CSS versioning as shown below;
    1. // return 'qa-styles.css?'.QA_VERSION;
      return 'qa-styles.css?v=2.1';
  3. Apply changes to your .css, and update root/qa-include/qa-theme-base.php to the server. 
  4. Inspect element to double check the changes is in effect.
    1.  <link rel="stylesheet" href="./qa-theme/YOUR_THEME/qa-styles.css?v=2.1">
