   Tried to log into my dashboard on my sandbox site, http://testlab.popularlogistics.com

   Got the following error message:

   Fatal error: Call to undefined function register_sidebar() in /home/popularl/public_html/testlab/wp-admin/includes/dashboard.php on line 13

   Looked in the forum - several people had this error message, apparently having to do with a plugin called "disable all plugins" - I don't have that installed.

   Tried to reinstall - my host uses Fantastico - so reinstalled 2.5.1 over what HAD BEEN a working install of 2.6

   The other installs of WordPress on my server are behaving themselves. I have FTP access - but don't know what to delete - except to delete everything and start over.

   Does anyone have any thoughts/suggestions?

   Thanks

   It could be the template your are using. Or a plugin.

   Do you think I should start by deleting the current template - and then plugins? Seems a reasonable strategy.

   Thanks for the thought.

   I would rename your plugins directory. That should first unload all plugins.
