Hi, guys,

I created an user and make it as blog author, this user is supposed to submit article in front end. 
I created an menu "add my article", type: item edit form.
Then, after i clicked "add my article" menu, the item edit form page pop up, but it doesn't show properly, it only shows from "title" to "Author" parts, below "Author" it is supposed to be the text input frame i guess, but i just can not scroll down, it stuck there. 

Attached is a pic for your referrence. 

 


please help, what can i do for this? thanks.
