Help solve this error: Class CommerceLicenseEntityController does not exist When I install the Commerce Licence module, in D7, I get this error. I think it might have to do with my Drupal installation, I'm not sure.
What steps can I take to find out what causes this?

The whole warning texts is (2 warnings):

Warning: class_implements(): Class CommerceLicenseEntityController does not exist and could not be loaded in entity_entity_info_alter() (line 1480 of /data/disk/o1/distro/002/drupal-7.54.2-dev/sites/testsite.com/modules/entity/entity.module).

Warning: in_array() expects parameter 2 to be array, boolean given in entity_entity_info_alter() (line 1480 of /data/disk/o1/distro/002/drupal-7.54.2-dev/sites/testsite.com/modules/entity/entity.module).
The error I got was a bit different, so this may not work for you. My error was

Exception 'ReflectionException' with message 'Class CommerceLicenseFile does 
not exist' in [filepath]/entity_bundle_plugin.module:46


I disabled the Commerce License module and renabled it. I can now clear cache without error. Hope that works for you if you have not solved the problem.
