The best method to rule out a rights issue is go to
Administration > Organization and Access > groups > New
a. Create a group named: casupport_testing
b. Add the resource(s) experiencing the issue
c. Add all the global rights or add the object rights, e.g. if the issue is with the project object
filter for the project-related rights by filtering for *project*
NOTE: It is best to add all available global rights
d. Have the resource log in and log out to check if the issue still persists
If the object can now be viewed, it is a confirmed rights issue.
Since a group can be easily deleted and resources can be easily added or removed from the group, this is best way to confirm an issue is rights-related.
