Archived:Reinstalling deleted Joomla 2.5 core extensions

This page has been archived. This page contains information for an unsupported Joomla! version or is no longer relevant. It exists only as a historical reference, it will not be improved and its content may be incomplete and/or contain broken links.

Some Joomla 2.5.x core components (Banners, Contacts, Newsfeeds, Smart Search, and Weblinks) can be deleted via the Back-end: Extensions > Extension Manager > Manage > (select + delete) Core component installation packages don't exist because it's too much work to maintain.

Reinstallation information per core-component

With some FTP & phpMyAdmin knowledge you will be able to reinstall deleted core components. In general, if you have deleted some core component by mistake, use the following steps to reinstall:

• Download & unzip the Joomla Full 2.5.x package of your current version
• Before following the next steps, backup your site (files + database)
• Re-upload the component's files for the front-end and the back-end (see info below)
• Re-create the reference to the component in your database with phpMyAdmin (see info below)

Next you will find the necessary information to reinstall a core component, all displayed in the format:

• Name
• Directories + files to re-upload (front-end and back-end)
• SQL query to run in phpMyAdmin to restore the reference in the jos_components table (note: assuming that your table prefix is the default jos_ )

Banners

Upload all files & directories under:

• /administrator/components/com_banners/
• /components/com_banners/

Use phpMyAdmin to run the following SQL statements to recreate the references (replace jos_ with your own table prefix!):
