To edit the footer in Joomla, you need to access the Joomla administrator panel and make changes to the footer module or template files. Here’s a step-by-step guide:

1. Log in to the Joomla Administrator Panel:
Enter the URL of your Joomla website followed by “/administrator” in your web browser. Provide your administrator username and password to log in.

2. Navigate to the Module Manager:
In the admin panel, go to “Extensions” in the top menu and select “Modules” from the drop-down menu. This will take you to the Module Manager.

3. Locate the Footer Module:
Look for the module responsible for displaying content in the footer area. The module might be named “Footer” or something similar. You can use the search or filter options at the top of the Module Manager to find the module quickly.

4. Edit the Footer Module:
Click on the module title to open the editing screen. Modify the content within the module as needed. Depending on the module, you might have options for text, HTML, or other types of content. You can add or remove text, links, images, or any other elements supported by the module.

5. Save the Changes:
After making the desired modifications to the footer module, click on the “Save” or “Save & Close” button to save the changes. The updated footer content will now be displayed on your website.

Note: If you can’t find a specific footer module in the Module Manager, it’s possible that the footer is being generated by the template itself. In that case, you need to edit the template files to modify the footer.

To edit the footer in the template files, follow these steps:

1. Navigate to the Template Manager:
In the Joomla Administrator Panel, go to “Extensions” in the top menu and select “Templates” from the drop-down menu. This will take you to the Template Manager.

2. Locate the Active Template:
Look for the template that is currently active on your website. It will have a star (*) next to its name in the “Default” column.

3. Edit the Template Files:
Click on the template title to open the template editing screen. Look for options or tabs related to editing template files. Depending on the template, you might find an option like “Edit HTML” or “Custom Code.” Click on this option to access the template files.

4. Find the Footer Section:
Within the template files, locate the section that corresponds to the footer. This section might be enclosed within HTML tags like `<footer>`, `<div id=”footer”>`, or similar.

5. Modify the Footer Content:
Edit the HTML or code within the footer section to make the desired changes. You can add or remove text, links, images, or any other elements supported by HTML and CSS.

6. Save the Changes:
After making the modifications to the template files, click on the “Save” or “Save & Close” button to save the changes. The updated footer content will now be displayed on your website.

It’s important to note that the steps for editing the footer may vary slightly depending on the template or module you are using. The options and settings provided by the template or module will determine the level of customisation available to you.
