MyBB Community Forums

[/align]I have tryed to install the Forum icons plugins, but it comes whit this bug, when i try to activete. Anyone who knows whats wrong?

MySQL error: 1060
Duplicate column name 'icon'
Query: ALTER TABLE liberaldebat_forums ADD (icon text NOT NULL)

link to the plugin ?

You already had some simular plugin activated ? Cause by default the icon column doesn't exist.
You need to run a query to delete the column and after that you should be able to activate.
Query to run:

ALTER TABLE <TABLEPREFIX>forums DROP `icon`

Change <TABLEPREFIX> to yours. If you didn't change anything during the installation it should be mybb_

That's a 2006 plugin. Be careful it probably isn't compatible.
