iphone blogger failure

I was so excited when I down loaded the new i phone blogger, Now I can blog whenever I want. I took the i phone with me to Denver when I visited my daughter and took lots of pics. and then wrote the blog complete with photos while at the airport. It was so simple, then hit publish and nothing... but PUBLISHING ERROR- the operation couldn't be completed. (Invalid category term.)  I thought no problem, I'll publish it when I get home to the computer- well the draft doesn't show up on my computer..but this draft (I just checked, shows up on the phone!) I went and typed in my problem on the help forum but have gotten no responses. Anyone have any ideas???
