Re-installing Joomla 1.5.x Core Components

[pe7er]

edit: For a more recent version see: http://docs.joomla.org/Reinstalling_del ... extensions


Did you accidentally delete any deletable Joomla 1.5.x core component in the /administrator back-end via
Extensions > Install/Uninstall > Components ?
(for reinstalling Joomla 1.0.x Core Components see this thread: http://forum.joomla.org/viewtopic.php?f=35&t=227323 )

You can delete the core components Banners, News Feeds, Polls, and Weblinks but there are no core component packages that you could use to reinstall the component. That's because it's too much work to create those every time after an upgrade (they have to be created for every Joomla version!). If you have some FTP & phpMyAdmin knowledge, then you might be able to re-install the deleted core components yourself by the following steps.

In general, if you deleted some core component by mistake, you can take the following steps to reinstall them:

• Download & unzip the Joomla Full 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
• Re-create the reference to the component in your database with phpMyAdmin

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_ )
