Now I have updated one of my sites to Version 2.7.0 I have an admin display problem for the tags. It seems that if you have more than one row of Tags or so many tags that it goes on to more than one line the tags overwrite the Author row.

Looks like it is a CSS fix but wanted to see if there was a better fix or I am doing something wrong.

Thank you for reporting this, you are correct it is a CSS fix.
We will correct this in the repo.

If anybody needs a quick fix, I made this change to the file /media/k2/assets/css/k2.css
about line 464 change to

ul.tags li {border-radius:3px;background:#d1e8fc;color:#0f4776;line-height:14px;list-style:none;float:left;clear:none;padding:0;margin:2px 2px 2px 0;font-size:14px;font-weight:bold;font-family:"Lucida Grande";vertical-align:middle;}

basically changed the padding to 0 so all the tags are quite small but readable and for me I never had more than three lines of tags.. Could have done more (border radius etc.) but works for me.

Hello Mike and thank you for sharing this,

Actually this has already been corrected:
