[Solved] auth/joomdle ERROR

Hi all,

I need a little hepl please,

i have installed Moodle 1.9.12+ and follow all the steps from "Installation" guide until the error on step:

"Step 3 Installing Joomdle in Moodle
Installing Joomdle in Moodle 1.9+
To finish the Joomdle Moodle installation, go to Site Administration -> Notifications.
You have now configured the Moodle side of Joomdle. Proceed to install and configure Joomdle for Joomla! "

Here my moodle instalation returns:

This script generated 22 warnings - Scroll to the first warning
auth/joomdle plugin needs upgrading

1050: Table 'mdl_joomdle_dummytable' already exists
1062: Duplicate entry '0-4' for key 'mdl_mnethost_hosser_uix'
1062: Duplicate entry 'auth/joomdle-field_lock_firstname' for key 'mdl_confplug_plunam_uix'

etc.

What to do?

I resolve the problem myself - here is the solution for further requests like mine:
Execute these queries in your Moodle database:

delete from mdl_config_plugins where plugin like '%joomdle%';
delete from mdl_mnet_host2service where hostid=0 and serviceid=4;
drop table mdl_joomdle_dummytable

An then, visit Notifications page again.
