Blank textarea when using ckeditor

Hello,

This is my last shot, I've been resarching all over internet for days and found no answer to my problem.

I installed ckeditor on my website, and everything aparently works fine (the instace's been created on the website, and even return data from database using $initialValue), but I just can't see the toolbar in the textarea.

Tried everything, including creating the textarea in html and then using $CKeditor->replaceall().

I would be extremelly grateful if someone could help me on this.

This the code (it's part of a major php code, but I think it's enough for helping me):
