3.5 upgrade disabled HTML editing, image posting, hyper links adding etc

Hi there,

I’m experiencing the some problems with an 3.5 update, such as I can’t edit the HTML (the text button is just not clickable), add hyper links, add images or add tags. I’m using Arjuna X theme.

Deactivating plugins didn’t help.

I’m sure the new version is a lot better, but right now I can’t fully appreciate it. because of these bugs.
Please help
