How to clear the cache in PrestaShop?
When making changes in PrestaShop they will often not appear right away due to old cached information. The solution is to clear the cache of the application.
PrestaShop version 1.6.x and above caches data using Smarty. Cached data is stored in the following directories:
cache/smarty/compile
cache/smarty/cache
img/tmp
all of which are located in your PrestaShop’s installation folder.
To clear PrestaShop’s cached data manually, delete the content of these folders except the index.php file and reload your website in your browser to take a look at the changes you have made.
To remove the files use FTP or File Manager in Site Tools.
You can also disable or clear the cache from your application’s admin panel > Advanced Parameters > Performance.
