I've tried to replace the logo.png but the old logo remains.
later tried to rename it to logo1 alongside proper modifications in style properties: header and navigation (change path directory), but the logo doesn't show up, it appears to be 404 error.
I'm pretty sure it's the right location, and about caching, any other change affects immediately.
BTW, how do i remove the h1 at the home page? because the h1 in the home page and the h1 in the node page is the same one, and i want it to appear only on node page.
