Reinstalling deleted Joomla 1.5 core extensions

Some Joomla 1.5.x core component (Banners, News Feeds, Polls, and Weblinks) can be deleted via the /administrator back-end: Extensions > Install/Uninstall > Components.

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 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:

INSERT INTO `jos_components` VALUES (1, 'Banners', '', 0, 0, '', 'Banner Management', 
'com_banners', 0, 'js/ThemeOffice/component.png', 0, 'track_impressions=0\ntrack_clicks=0\ntag_prefix=\n\n', 1);
INSERT INTO `jos_components` VALUES (2, 'Banners', '', 0, 1, 'option=com_banners', 'Active Banners', 
'com_banners', 1, 'js/ThemeOffice/edit.png', 0, '', 1);
INSERT INTO `jos_components` VALUES (3, 'Clients', '', 0, 1, 'option=com_banners&c=client', 'Manage Clients', 
'com_banners', 2, 'js/ThemeOffice/categories.png', 0, '', 1);

News Feeds

Upload all files & directories under:

• /administrator/components/com_newsfeeds/
• /components/com_newsfeeds/

Use phpMyAdmin to run the following SQL statements to recreate the references:

INSERT INTO `jos_components` VALUES (11, 'News Feeds', 'option=com_newsfeeds', 0, 0, '', 'News Feeds Management',
'com_newsfeeds', 0, 'js/ThemeOffice/component.png', 0, '', 1);
INSERT INTO `jos_components` VALUES (12, 'Feeds', '', 0, 11, 'option=com_newsfeeds', 'Manage News Feeds', 
'com_newsfeeds', 1, 'js/ThemeOffice/edit.png', 0, 'show_headings=1\nshow_name=1\nshow_articles=1
\nshow_link=1\nshow_cat_description=1\nshow_cat_items=1\nshow_feed_image=1\nshow_feed_description=1
\nshow_item_description=1\nfeed_word_count=0\n\n', 1);
INSERT INTO `jos_components` VALUES (13, 'Categories', '', 0, 11, 'option=com_categories&section=com_newsfeeds', 
'Manage Categories', '', 2, 'js/ThemeOffice/categories.png', 0, '', 1);

Polls

Upload all files & directories under:

• /administrator/components/com_poll/
• /components/com_poll/

Use phpMyAdmin to run the following SQL statements to recreate the references:

INSERT INTO `jos_components` VALUES (10, 'Polls', 'option=com_poll', 0, 0, 'option=com_poll', 
'Manage Polls', 'com_poll', 0, 'js/ThemeOffice/component.png', 0, '', 1);
