I’m not sure if you are saying you are having trouble doing these things or that you know how to do these things but the buttons are not working.
If you don’t know how to do these things here is basic instructions (if these things just aren’t working I guess my help is useless 🙂 –
permalinks: Once you save your post the permalink will appear under the title and can be edited but if you would like to do it in one step you can fill in the slug field with your desired slug for the permalink. I had to go into screen options and check slug. It was not visible by default.
tags: you should be able to add tags by typing them into the tag box. If you can’t see the tag box you may need to check the tags option in screen options to make it visible.
private: you can set the visibility option to password protected or private before you publish it.
thank you for your answer. 🙂 i know how to do it, but from this morning i can’t anymore.
I can’t do anything of this things, i have no idea why.
for example, i push the key to change permalink, but nothing is happening. the same is with with tags and private. 🙁
