问题
I've been trying to change the product/catalog.twig file, to remove some unnecessary buttons such as the "add to wishlist" and "compare product" options, which are just useless for the store I'm attempting to make.
On the theme editor, I've removed the two buttons from the .twig file, yet the changes aren't showing on the store. I've heard it might be an issue with caching, like it's bringing up the old site. So I deleted the cache from the storage folder, yet the problem still persists.
回答1:
In OpenCart 3.0.2.0 there is button with a gear icon in admin dashboard. It open up a modal that allow you to clear cache or disable cache.

First of all, Its better to use the OC's builtin Theme Editor to make any change in any template file. In-case you want to change something directly using FTP Client or a file-manager, you must know the OpenCart Structure a little :-)
Anyway, bellow are the few things that can be helpful for anyone looking for the solution.
1) You have enabled the cashing, you can clean it as described by @DigitCart - Alternatively, you can clear all the files in following folder YOUR_STORAGE_DIRECTORY/cache/* (Don't remove the cache folder)
2) Probably you are trying to make change in a file that is modified previously by an Extension, You can find the modified files under YOUR_STORAGE_DIRECTORY/modification/* You can make a small extension and install it through Extensions > Installer to make changes in these files. OR, you can change these files directly via FTP, but its not recommended.
