Many of our customers experience errors related to making changes in their PrestaShop and said change is not reflected on the website, such as installing a module and that module starts to fail, among many other errors that can occur in PrestaShop, they are usually solved by clearing the cache, which in general terms is like restarting a computer.

The cache:

The cache is something wonderful for web pages, because they optimize them a lot, so that when a page is displayed, if it does not have the cache, it has to be built completely and if the cache is activated, the product of that construction is saved in a series of files so that it does not have to be rebuilt, but when a request is made to display that page, PrestaShop will not build it but will transfer said cache and this process is very fast.

What should we do to clear the cache and rebuild the page, thus refreshing all the changes in PrestaShop? We will go to the Backoffice of our PrestaShop.

And in the menu on the left, a series of elements will appear, in which we will focus on Advanced Parameters, then the Performance option will appear and this is the important tab that we are going to use.

Once inside it, a blue button will appear at the top right that says "clear the cache", we will click on that button to refresh said cache and it will refresh the changes. And can we see the new changes now?

Yes and no, it depends on the cache of the browsers on our computers, because they also save the page in cache so that the pages we visit most often go even faster and it would be basically solved by pressing Control + F5 and refreshing the cache of our browser so that it now takes all the changes and we can view them correctly.
