I’m not one of your more capable so apologies if I’ve overlooked something obvious
I only ever use the theme straight out of the box with minimal amendments due to my lack of the necessary skills
I created this site http://www.factoring-broker.org.uk/ which works just as I want but when trying to replicate everything for a second site I cannot see how to make the logo full sized as all I can get is a small logo in the top left corner http://invoicefactoring-uk.co.uk/test/
Unless I have missed something obvious I have checked the settings from the first site to the second to ensure that they are both the same but no amount of fiddling about will enlarge the header
