A little testing with disabling all media modules, and after re-enabling Media Gallery I get this when opening the Galleries:

Notice: Undefined property: stdClass::$media_gallery_media in media_gallery_node_load() (line 198 of /var/www/example.com/drupal-7.0/sites/all/modules/media_gallery/media_gallery.module)

Best regards,
Ao

I'm getting the same errors:

Notice: Undefined property: stdClass::$media_gallery_media in media_gallery_node_load() (line 198 of {path}/sites/all/modules/media_gallery/media_gallery.module).
Notice: Undefined property: stdClass::$media_gallery_columns in media_gallery_view() (line 278 of {path}/sites/all/modules/media_gallery/media_gallery.module).

Warning: Division by zero in pager_default_initialize() (line 282 of {path}/includes/pager.inc).

where {path} is the path to my drupal installation.

** Edit: I forgot to say I am using the 7.x-1.x-dev files for media and media_gallery
** Edit: At the /admin/config/media/galleries url, I get a white-screen with this error:

Fatal error: Cannot access empty property in {path}/modules/field/field.attach.inc on line 198

On /node/add/media-gallery, I get:

It loos like work on this issue is going on under the following issue:
#1015580: Media entities : Cannot access empty property in field.attach.inc line 677

I am still getting this error with the latest version of media and media gallery. I do not see references to this problem in the #6 post above.

Is anyone else still seeing this error?

Same problem described in http://drupal.org/node/989752

I have the same problem as #11 AND #4

I had the problem right from the beginning. This is extremely frustrating.

I'm running Drupal on what is presumably a very standard platform: A Dreamhost shared-hosting account running on LAMP.

Warning: array_filter() expects parameter 1 to be array, null given in media_gallery_view() (line 252 of /home/public_html/sites/all/modules/contrib/media_gallery/media_gallery.module)
