I am not too sure to be honest since you have customized the layout. I believe it is probably a custom filter but it's best that you try switching back to the default theme and see how it looks like originally.

Hello! I switching back to the default theme, and i have the same link
This link is available only for one user, and I do not understand how it came there

Ah okay, it could be from your friend list. Go to your friends section and see if you have a list called "test" ?

Oh, right ... ty! And what it shows? News from the people from the list?

Hi Tima,

It actually will shows feeds from the 'test'

Nice!
Thank you!

You are most welcome Tima
