PrestaShop uses Smarty cache. Its cleaning is required if changes were made on the site, but they are not displayed.
index.php
in directories with cache files is not allowed. In this case, the site may malfunction.
For manual cleaning, you need to delete all files except index.php
, from directories:
/cache/smarty/compile
*cache/smarty/cache
*img/tmp
You can perform these actions using filemanager or any FTPclient.
