How to remove the two dark grey bars that come under the pages menu and above the category menu? Changing its color to the same as the bg would work too.

Can you supply a link. What those bars are depends on which beginning style you used.

Ok, this is very early in the design, but here it is: http://www.pinkycupcakes.com.br/blog/

It's the two dark grey horizontal bars at the header area, some 5 pixels wide.

go look thru FAQs at http://forum.bytesforall.com/forumdisplay.php?f=43

Those are borders on the image container. I think that may be in ATO>Add HTML/CSS Inserts>CSS Inserts but check through the various area of the theme options and look for border-top: 5px and border-bottom: 5px

Thanks a lot, this theme and its support rock!
