"o" in Source text

Please have a look at www.my-businesswebsite.de/

There i find a "o" in the Source text between the menu entrys.
How can i deactivate this?

Hi
I don't see it in your page. Is it solved ?
CEd

you see it only in Source text.
And also at mouse over that there is a distance between menu entrys

first you have posted in the Accordeon Menu CK section of this forum and I don't see any on your page, only a Maximenu CK
in this menu I don't see any problem, also not in the source code

please send me a screenshot

PS : also try on another browser to see if you have the same problem

See screen

it is with 4 browsers the same
