Thanks for your help.

PHP version: 5.5.23
Drupal core version: 7.38
ubercart version 7.x-3.8
Are you using dev branch of this module? Yes. I also tried the 7.x-1.2 with the same result.

All current modules, except accountmenu is dev version.

Oh, and uc_disable_product is from this comment: https://www.drupal.org/node/2051399#comment-8247671

I don't know what changed, but it works now after several module changes. Thanks for checking.
