   Hello

   I have made an upgrade from 2.5.1 to latest - the worst idea I had since the late 80's by the way.

   After I upgraded the nextgen-gallery plugin to "latest" I got the below when I try to make changes in previous articles.

   I hope someone here has a super FLX idea what to do. My blog is kind off dead at the present

   Thank you

   I don't know if I would say it is a database error at this moment, having more info on what your site is running would help. Example, version of MySQl if that is what you are using.

   I will just through a few things out since you went from old to knew and I don't know if your WordPress theme is updated to run 2.7.

   I would say to look and see if you have the following in your header.php file. <?php wp_head(); ?>. I think that would be a start.

   I would also make sure that you have the proper permissions set up for the gallery folder you have made, ensure that if you are using the .htaccess that there is nothing that would be restrictive to writes that need to be made to the gallery folder.

   I hope that you have a backup of your database, you can always restore then move ahead again.

   I hope some of what I suggested helps, trying to throw a life line out to you, I know what it is like to have a site that is in the dark.

   Since the 90's by the way: search could be your friend.
