Theme logo not working on static home page

Hi

I have been tasked by a friend to help her out with building a website for her business… I have never done anything like this before, neither of us have a clue about coding, but WordPress seemed like an option that with some learning, could be possible.

But I have hit a problem

She started building it, and installed a plug in, which looks to be quite old called Theme Logo which gets her logo on the top of the page
I have since installed a static home page, and this plug in is not working on the static home page, which ruins the aesthetic somewhat

I spent hours on this yesterday trying to work out how to sort this, but I feel like perhaps the plug in just doesn’t work with a static home page
And to further the problem I cannot get rid of the plug in and use something else, because clearly the coding is still looking for something related to it when I have deactivated it and a fatal error occurs (though not on the home page…)

Can anybody help? Either to get the plug in to work on the home page, or to get rid of it entirely so I can have a uniform look across the site.
Thanks
