Read this if you are thinking about installing a Joomla! 3rd Party Extension
Fools rush in where angels fear to tread!
There are thousands of extensions to choose from in the Joomla! Extension Directory.
But not all are to be recommended, either because they are untested or not well supported by their developer.
Others may result in your website becoming less secure.
It is important to use only extensions that can be trusted and are regularly updated by their developers.
Before you install and use any third party Joomla! extensions we recommend that you undertake the following checks.
Undertake a full backup of your website
You should always do this before installing a third party Joomla! extension.
If your website later malfunctions you can then restore your backed up version of your website.
The Joomla! Vulnerable Extensions List
Always check that the extension you want to use is not on this list.
Periodically re-check.
