Yes, basically you want to do an "Export" from phpmyadmin (use the SQL format). Then if something went wrong you could always a new database and "import" the data to get back to the last good state.

I've done this successfully from some of my cpanel managed sites.

That did it! Thanks.

BTW, for backing up the databases using mysqldump, is that something I can execute

from phpmyadmin? I am using a cpanel access to the site. I wasn't seeing that

as a specific application in the cpanel or the database pages.

I have also had these periodically, mostly when I've been copying cloning or importing database sites. The cause is very loosley described as stale sessions. If you have mysql administrative access,consider executing the following query:

DELETE FROM sessions

This will remove all entries from the session table. The session table only contains information about people currently logged in or connected to drupal, so it may be safely deleted, especially during times of low activity.

I don't know the root underlying cause but this should get your site back up and running. Without risking content.

As always, it's good to make a mysql backup using mysqldump prior to executing scripts like this.

Good luck,

Dave

Bruce,

I get these every now and then on a number of sites and servers. I couldn't find much info on it and the sites still seem to be running fine. I would love to get details on how to resolve.

Hi all, My drupal site suddenly started displaying an error that I cannot make sense of...nor do I know what to do. I have been using Drupal to run a poetry magazine online and a writer's community. Poetry submissions come in via the drupal submission queue. I haven't made any changes to the site code or any admin changes or any changes at all to the site. Thus the site error comes as quite an unexpected and confusing surprise. The error message is listed below... I hope that this can be fixed. I don't want to loose the many poems submitted and published and those awaiting publication. It would be over a year's worth of published poems that could be lost. Can someone help me, please, with this problem. The error is included below. Please let me know if you have any idea what I can do. I had thought that some backups were being made by someone helping me maintain the site but I cannot be sure if there is a recent backup available on the site. Error message>>> Fatal error: Duplicate entry '0' for key 2 query: INSERT INTO sessions (sid, uid, hostname, timestamp) VALUES ('8cbce4316d9b4797ef37e81fee84a52f', 0, '68.213.148.90', 1168370359) in /home/brucew/public_html/home/includes/database.mysql.inc on line 66 Thank you, Bruce
