Suburbia theme header and duplicate posts

Hi,

I’ve done a quick search to see if anyone has asked this before but couldn’t find anything, so apologies if it’s already been answered somewhere.

My site https://www.mancunianvintage.com uses suburbia theme.

I’d like to change the text on the homepage where it says ‘Suburbia theme’ to ‘Mancunian Vintage’.

Is this possible? If so – how?

Also, I seem to have duplicates of my stickied posts – is there anyway of sorting this? I’ve installed duplicate post remover, but it doesn’t seem to do anything.

I’m sure there must be some for of CSS editing required, but I’m very much a noob at this sort of thing (but willing to learn!)

Thanks for having a look,

MV
