The following module is missing from the file system: variable_realm_admin [#2798381]

Hi,

I just upgraded to Drupal 7.50 and now get the errors:

User warning: The following module is missing from the file system: variable_realm_admin. In order to fix this, put the module back in its original location. For more information, see the documentation page (link is external). in _drupal_trigger_error_with_delayed_logging() (line 1128 of /home/xxxx/www/sandbox/includes/bootstrap.inc).

For more information, see the documentation page (link is external). in _drupal_trigger_error_with_delayed_logging() (line 1128 of /home/xxxx/www/sandbox/includes/bootstrap.inc).

I can't find any help on this issue and have removed the module, deleted it from the filesystem, cleared the cache and also reinstalled and I still keep getting it .

Can anyone help me?

Thanks
Rich
