Custom event details:

What database are you running? The problem is that the media recycling bin hasn't been added into the database. Check the database, it should be in the umbracoNode table with an ID of -22

Hi slace,

Thank you for your reply.

I work with MySQL 5.1 and indeed I looked at the umbracoNode table and ofcourse id -22 is missing.

Is there any way I can insert it manually?

Could you paste here the required values please?

Regards,

Gal.

Sorry, it's -21 (looking into the SQL scripts). I know there were some problems/ missing parts of the MySQL script for 4.5.0 which have been rectified in 4.5.1, so I'd suggest trying that upgrade.

Just updated to V4.5.1 and I have the same problem media tree is empty and an exception in the logs.

Looked at umbracoNode and there is a record with nodeobjecttype = 'Recycle Bin' and id='-20'
