How to Remove a Joomla Powered Site (5 Steps)

Uninstall all Joomla extensions before removing the actual back-end software. If you do not have any extensions, skip to Step 3. To uninstall extensions, login to Joomla. If you do not remember your Joomla login information, consult the confirmation email you received when installing the software. This email contains the personalized link that will allow you to sign-in to the Joomla service.
Click the drop-down menu in the left-hand side of your Joomla screen. Select 'Extensions' from the menu. Click the name of each extension that you have running. Joomla will then display the extension's settings page. Click the uninstall icon, which looks like a trash can. Joomla will alert you when the uninstall process is complete. Repeat for each extension.
Launch your FTP software (e.g., Cyberduck for Mac or Fetch for Windows PCs). Login to your web host server. Wait for the FTP software to load a list of all of the files and folders for the web site. Right-click the folder entitled 'Joomla' and select 'Delete' from the pop-up menu. This will delete all of the program files for the software.
Login to your web host account and access the MySQL database page. The location of this setting varies according to your web host provider. If you are unsure of where to find the settings for your databases, contact the customer service department at the hosting company.
Delete the database you used to operate Joomla. Joomla is now completely uninstalled.
