Miuna News Alignment Error

[Gabbar]

I am using Miuna News. Its just a great plugin. But I want a support about its alignment.
I am unable to align it. As shown below when I hover on live feed the live feed will show like this. in MyBB Pro.
while on other theme there is no error lyk that.

May anyone help me with that. As how can I align it jst below the live feed link.

Thanks In Advance.
