Dear.
1. My mean, because the main feature of package is Post Job (for job package) or Post Resume (for resume package) and in Jobmonster default:
If setting 'Post Job' is 'Employers' then all Employer can view resume in spite of setting 'View Detail Resume' is 'Employers with Paid Packages' because Employer don't need package to post job and Jobmonster will don't check package on all action of Employer .
You can check on your site will Jobmonster old version.
In new version, we're disable select 'Employers with Paid Packages' of setting 'View Detail Resume' when setting 'Post Job' is 'Employers' to clearly Jobmonster's logic works.
2. I have check again. i see if the setting 'Post Job' is 'Employers' mean Employer don't need package to post job and the menu Manage Plan will not display.
Best regards.
