if i use a shorcode in the web page like [ninja_form id=3] then it is ok
if i use the menu on the right and select the form through “append ninja form menu” then it is doubled.
so it looks lika a bug but i have a workaround
thank you for your help
absolutely sure. the page is empty and only the “append ninja form” field is set for the form to be displayed. the form itself does not have any settings. even if i create a 1 textbox form it is always doubled
i had to disable all the features of w3total cache plugin then disable and delete the plugin. skmply disabling it is not enough, you need to disable its settings first otherwide it wont be disabled just by disabling the plugin
