Hi there,
just installed the comment component, and received this:
There was a problem with your installation

Install error: DB function failed with error number 1054

ALTER TABLE `vpo_comment` ADD `component` VARCHAR(50) NOT NULL default '' AFTER `contentid`;

Any ideas?

Have you ever in the past installed our extension?

Sorry,
I just discovered what was going wrong...
I migrated from Mambo to Joomla and didn't drop the two existing mos_comment tables of the old installation.
However, thank you very much for the fast answer.

P.S.: I saw a small problem in the module... you should say, in the explanation text, that the selected contents are excluded. Normally people think that the unselected ones are excluded...

What parameter are you referring to?
