Sorry about that error, yeah it’s fixed after I updated WP to latest version.
I am sure adding a page where admin can see all timseheets would be super use full. The way you gave also serves the purpose, but it’s little indirect way. Rather it should be like at first show list of all timesheets to the admin and then can give options to filter by clients and projects or by name of the employee, date range etc.
Anyway, thank you very much for developing this plugin, and helping out here.
