Menu problem – duouble navigation

Is that just a heading or is it another navigation?

Try and add this to your css file

.entry-header
{
display:none !important;
}

I would not fall for it ! Thank you cdhishna , andrew!

Part “Blog” in my navigation is not page – this is “catygory”.

In catygory your way does not work.

@twojasciana: So you don’t want the text ‘Kategoria: Blog’ at the header part that is seen when ‘blog’ is opened. Is that right? If so then this css will do it for you.

h2.page-title {
    display: none;
}

Please elaborate your issue in case i’m confused.

Great!
Your’s support is exact. Thank you, but now i have onlny line.

For that, just put this css in your ‘Advanced’ section of theme options.

.page-header:after, .entry-title:after {
display: none;
}
.entry-header .entry-title {
display: none;
}

Thanks!

I pasted your cod in Advanced’ section of theme options , but now line is a fine.

Apology for not noticing that fine line before. Anyways, for that fine line, this css will do it for you:

.page-header, .entry-title {
    display: none;
}

Thanks!
