It might be necessary to clear the cache that Prestashop keeps. To do so, execute the following steps:

  • navigate to your prestashop directory on that server
  • except for index.php, delete all files and folders under ./cache/smarty/cache/ and ./cache/smarty/compile/

  • as for the .htaccess file under the Prestashop root: delete it
  • once deleted, login to your admin portal and navigate to Preferences > SEO & URLs and simply hit the Save button (you might have to scroll down a bit)
  • this re-generates the .htaccess files with the updated values for the media server URLs specified in step 2.
