Got message of :user warning: Duplicate entry '0' for key 'PRIMARY' query．．．．．．．

I'm also experiencing this error. Was able to fix it by checking out the panels_pane table, there were some bogus rows in there. Also had to empty out the panels_object_cache table as well before the error went away.

With the release of Drupal 7, Drupal 5 is no longer supported.

I just got this in D7.

I'd really like to save this panel... ;-)

The entire code base has pretty much been rewritten. Whatever caused this problem in 5.x is unlikely to have caused this problem two full Drupal versions and one full Panels version later. This needs to be opened as a new 7.x-3.x issue.

Same problem (with Drupal 7) - have you opened a new D7 issue, seanr?

For the benefit of anyone who stumbles across this from a web search:

I was also seeing this error in Drupal 7, but it seemed to fix itself after I re-exported the feature containing the panel, so I suspect I either had a problem with my feature (e.g. two panels with the same id) or a conflict between my feature and the database. I don't know if either of those things should be possible, but I've stopped investigating as I can no longer reproduce the problem.

I am having this issue and stumbled upon this post by doing a websearch.

Using Drupal 7.

What do you mean when you say that you:

re-exported the feature containing the panel

Features is a module that allows you to save a copy of parts of your Drupal site (e.g. panels) as PHP code. I "saved" my panel as a Feature, then restored the panel from the Feature.
