It can be easily done in admin mode with a tool called 'Plug-in Manager' which can be found on the 'Config' tab.
The way of hiding the tabs is slightly different for various versions of EPiServer. I tested it in with 5.1.422.256 and 5.2.375.133 versions.
Hiding 'Workflow' tab:
- in 5.1.422.256 version - choose 'EPiServer.WorkflowFoundation.UI' plugin, switch to 'Overview' tab and deselect 'Workflow (EditPanel)' option in the 'User Interface' section.
- in 5.2.375.133 version - choose 'EPiServer User Interface' plugin, switch to 'Overview' tab and deselect 'Workflow (EditPanel)' option in the 'User Interface' section.
I you need to hide 'Statistics' tab (in both versions) choose 'EPiServer User Interface ' plugin, switch to 'Overview' tab and deselect 'Statistics (EditPanel)' option in the 'User Interface' section.
It can be slightly different in the version of the EPiServer which you use, but the general rule is the same.
