Problem with Joomla 2.5, moodle 2.3+ and Joomdle ( SOLVED)

Hi Guys,

I have problem on logon in joomla, in my intranet.

0: Error Creating User -DB function failed with error number 2
Could not connect to MySQL.

Is showing this error message every time I log on joomla,


But I can log in and use with the moodle joomla, want to know why this message is appearing uncomfortable at any time.

can you help me?

thanks

the problem was with the JFUSION PLUGIN, the joomdle doesn´t work well with this extension.

I disabled the Jfusion extension, and the joomdle returned to work well.
