I have created a module which registers a new Content Type.
If I enter an existing Page Alias, I get the following message:
My module does not create a tab "Options", so, in my opinion, the default message should not mention "Options" tab.Alias has already been used on another page. Change "Page Alias" in the "Options" tab to something else.
You can experience the same issue if you are using module "Jobs".
Bug in CMSMS 1.2
