Can't install sh404 on Joomla 1.5

[kev1]

Hi. I can't install sh404SEF on Joomla 1.6. I get this error:

     * JInstaller::install: SQL Error. DB function failed with error number 2006
          MySQL server has gone away SQL=CREATE TABLE IF NOT EXISTS `jos_redirection` ( `id` int(11) NOT NULL auto_increment, `cpt` int(11) NOT NULL default '0', `rank` int(11) NOT NULL default '0', `oldurl` varchar(255) NOT NULL default '', `newurl` varchar(255) NOT NULL default '', `dateadd` date NOT NULL default '0000-00-00', PRIMARY KEY (`id`), KEY `newurl` (`newurl`), KEY `rank` (`rank`), KEY `oldurl` (`oldurl`) ) TYPE=MyISAM;

                                                ) TYPE=MyISAM;

Can anyone help?

Beats me. Maybe someone can throw some light on this.

We don't use J1.5 exactly because of this. Too young.

Do you get this error repeatedly? Or just this once. Maybe you've installed it in the meantime... Doesn't seem to be a Joomla 1.5 error.

Sorry to be negative on my first post back there.

As no one has helped you out I thought I'd look again.

The DB error looks like there is already some data in those tables and the install won't write to them because of that. You should manually uninstall any previous SEF plugins, then try to install again, deleting the tables manually if necessary.
