I am using PM 3.2.1 community version.
I followed the instructions in https://wiki.processmaker.com/3.1/Workspaces#New_Workspace_Form to create a new workspace.
I login as the system administrator with PM_SETUP_ADVANCE permission.
Then I changed the URL of the browser (Firefox) to http://127.0.0.1:81/sysMyCEC/en/myCEC/install/newSite where I would like to create a new workspace MyCEC with the default skin myCEC.
However, the browser went to the login page with error message "ERROR: You have specified an unavailable workspace.".
I revised the URL to http://127.0.0.1:81/sysMyCEC/en/neoclassic/install/newSite but the same error message came up.
Grateful if I can be advised what's wrong with my work.
