Just installed UserForms 0.4-122 on a SS 3.0 site. The readme indicates the version requirement to be "SilverStripe 3.0"
Copied module to site root /public_html/userforms
Ran /dev/build
Created a new page as "User Defined Form" and although I see "Form", "Form Options" and "Form Submission" tabs, the "Form" tab is blank?
