TOPIC: How to uninstall a 2.5 component from a 3.0 site.

How to uninstall a 2.5 component from a 3.0 site. 1 year 1 month ago #67114

I recently switched from building a Joomla! 2.5 site to building a Joomla! 3.0 site. I'm glad that I did, because I think making the change now, in the early stages of development, will be easier than making the change 2 years from now.

I mistakenly installed the Joomgalaxy extension on a 3.0 site. The JoomGalaxy.com site is offline for 9 days, so I won't be getting much help from them. But I'm fairly certain that the Joomgalaxy extension was a 2.5 component.

The install seemed to work, and the component menu appears under "components" in the back end admin panel.
Attempting to access the Joomgalaxy interface, however, yields:
"Fatal error: Class dashboardController cannot extend from interface JController in /home/myusername/public_html/mywebsite.com/administrator/components/com_joomgalaxy/controllers/dashboard.php on line 15"

The plugins do not appear in the system plugin manager, although the Community Builder 1.9 plugin manager did show the one CB plugin.

My question is this:
How can I uninstall the component manually? Would there be files in the cpanel file manager directory? Do I need to search the database for the relevant tables?

or

Can I just leave it alone, like space junk, and hope that it doesn't collide with any of my other extensions?

Hi TaiChiWizard,

Go to:
1) Your Admin Area
2) Extensions
3) Extension Manager
4) Manage
5) Search for the extension(s)
6) Uninstall

Hope this helps! Let us know if you have any questions along the way.

Kind regards,
Nick

Boy, do I feel sheepish.

I had gone to
1) Admin Area
2) Extensions
3a) Plugin Manager
3b) Module Manager (when I didn't find the plugin)

I did not realize that "Manage" was actually a third option, and not a redundant link.

Thank you.
That is why I'm enrolled.

You're welcome, Ian!

No problem! It would be good if Joomla had some redundant linking from Plugin Manager, Module Manager, etc, to the Extension Manager Manage area :) Think of Plugin Manager, Module Manager, etc, as the day-to-day management and the Extension Manager Manage area as just the "one-time" management area (e.g. Uninstall).

Kind regards,
Nick
