Sandbox

this is the error I get when clicking "extentions" link.

mossession::store failed
DB function failed with error number 1062
Duplicate entry '1-' for key 2 SQL=INSERT INTO jos_session ( `session_id`,`time`,`username`,`gid`,`guest` ) VALUES ( '71efdbd1e12aaac17ab431188c4b9746','1182873490','','0','1' )

Looks like the sessions table is corrupted.

Yes, we are aware of this and working to resolve it.
