I can't edit template

Hi everyone,

i have a problem with TagDiv Composer. I have 2 websites, the first one is actugeekgaming.com, on this one i can edit every page or post with tagdiv composer. But the second one, resumetonlivre.com, i can just edit the home page but not all the website and i don’t know why. It seems that i have to DL a pre-designed template from the cloud library but i can’t.
The goal is that i can change my post template and remove author box from posts or other things.

Here is some images :
