Problems with writing in a blog post

I have a problem with my blog post page. I’m using theme Maple from Ruby and suddenly I can not longer write or upload photos. The toolbox recently disappeared from the editor site. I have checked every plugins and it’s nothing wrong with them. I also try to change to another theme and then everything works just fine. That means there is something wrong with my theme (Maple).
I really hope anyone understand my problem and will help me fixing it.
