Cache errors still keep apearing after clearing FTP folder /www/var/

[manuel987]

Good Afternoon,

I got a problem wich is when i remove the FTP Folder /www/var/cache and, after that, i do some changes on the Prestashop Store and clear the cache in the backoffice (got Smarty Cache ON, model compilation --> never recompile template files and CCC ON) i got sometimes error 500 and i dont know if there is another way to solve the clearing the cache problem that i have. ( One other problem related to the cache is when i regenerate thumbnails and see the changes on the product list in the homepage in my pc it goes different in other pc's and i solved it by clearing the cache)

Hi,

First of all, don't just delete the www/var/cache folder.
Delete the content of t he following folders instead

• www/var/cache/dev/smarty
• www/var/cache/prod/smarty

And if you have changed anything that is related to overrides delete

• www/var/cache/prod/class_index.php
• www/var/cache/dev/class_index.php

So removing the contents of www/var/cache/dev/smarty and www/var/cache/prod/smarty will solve the cache problem i have  ?

I prefer to rename folders and files before deleting. Test refresh & empty caches and if all checks out delete.

Good question...

I looked into it, PS docs (couple of years ago) described it like this, but it's not needed anymore.. 
So yeah ignore my post 😅

What is the point of backing up your cache?

Once you have deleted all files and folder of your shop you'll create an error. Some parts have to stay.

thanks for the answers but i found another problem well sometimes i clear cache i get an error saying that prestashop cannot find Tools.php i checked that i have no Tools.php in the store and can i ask where can i get the default Tools.php for prestashop version 1.7 so i can put via FTP (unless it gives me more errors)?

prestashop cannot find Tools.php

Which one? There are 2, one in src/adaptor and the other Classes/.

strange i have both but the problem still comes sometimes when i clear cache. The error i have is this one ( Fatal error: Uncaught Error: Class 'Tools' not found in /var/www/vhosts/soundtaste.shop/httpdocs/classes/db/Db.php:794) but if clear cache twice the error does not show up so i think its a bit strange
