Why clear the browser Cache after installing an update to an Extension?

Simply put: Because it is a Best Practice to follow to avoid making assumptions that any new update has bugs or issues.

The StackIdeas Team team works hard long hours to fix bugs, add new features, and make many changes to the extension to accommodate various template configurations for thousands of users, and with this comes changes to the Extension files that can compromise your live website, making you think there have been new bugs added to the Extension update. This is why you have been asked to “Clear your Cache” after installing a new update to an Extension.

What does clearing the browser cache do? What is my 'cache' and why should I clear it?
Your website consists of a composition of thousands of files, and all websites are loading tons of files at once to display content in your browser.

Every webpage Browser has been designed to speed up the loading process. The first time you visit a website, the browser you are using will 'Save'files most often viewed on the website in what is called the Browser Cache. The Browser makes it possible to display website files stored in the browser cache much faster than it can pull fresh files from the website server. Each time you visit this website, the browser will use the 'cached files' to cut down on webpage load time.

So why is it important to always clear the Browser Cache after installing an extension update?

When the StackIdeas Team makes updates to the extension, they often make changes to a number of files, and since these files make up how your website is displayed, if you DO NOT CLEAR THE CACHE, then the old files are still being served up and you won’t see the most recent changes. This usually results in weird errors and issues, making users think or assume that the new updates to the extension has bugs and new issues that need to be fixed. Then people post issue or bugs requests on the support site, and this results in the StackIdeas team having to politely ask the following:

Please clear your Browser Cache. - this will clear out the old files being used, to update the new files. This usually resolves most issues.

I am just like many other people - I have posted what I thought was a bug report and it turned out to be a Browser Cache issue. I now make it a habit to clear the browser Cache after any update to files on my site.

There is a Silver Lining in Clearing your Browser Cache - less time spent by the SI Team on asking people to clear their Browser Cache means more time spent on creating cool new features for their extensions.

Joomla documentation: Site Maintenance - Clear Cache

How to clear cache files from the cache folders if enabled under the Site Global Configuration settings.

How to Access

To access this screen:
Select Site → Maintenance → Clear Cache from the drop-down menus.

Description

This tool will delete all Cache files from the cache folders - including current ones - from your web server. As admin functions are cached too, some cache folders might appear as if they were not cleaned because they get recreated before cache content is rescanned after this action.

Click the 1st reference link below to access Joomla documentation page for clearing Joomla cache.

Peter,

Some suggestions for you and others that want to make sure Members of your site understand the importance of clearing the browser cache after you make any major updates to the site. Create a HELP FILE and use the text and images below to save you time.

I have included the text of this Tutorial (below) for you to add to an article page or new discussion on your site. I have changed all the references to the step number and header graphic image files from referencing my site and you only need to change or add the necessary information for yoursite.com. Help files will save you a TON OF TIME educating your members.

I would like to create more generic content Help files for EasySocial and EasyDiscuss and EasyBlog that customers can use on their own sites. I just need to allocate the time. Perhaps I should start on this tomorrow.

Here is what you need to do to use this text as your own Help Article for your site members :

1. Create a folder in your Images folder on your site. Name the folder: help_images
2. Upload the attached images below to the help_images folder. This folder will be in this path on your site:
http://yoursite.com/images/help_images/ > - all files will reside in this folder.
3. Modify the Help Article text below to suit your site needs. You can change any parts you want. Just make sure your images are referenced properly in their proper path on your server.
4. Test out the Help article or Discussion, and if it looks good, then create an HTML Module and some text or a link that directs your Members to the Help Discussion or the article on your site.

Copy this text to your discussion or article: Modify as you see fit. Make sure all image links work properly so the Step numbers show up and the headers show up in your article. Make it available to your members. I have also included the Help Text below in this attached rtf file:

clearcache_helptext_01.rtf
