Good evening, I am new to DNN and I am trying to help my friend out with her Real Estate site. She had it made by someone a few years back, and can no longer get in contact with them, I am trying to help her with the site using the Admin account I was given for the site.

Question 1: I am looking to change the logo. So I went into site settings, found the logo, but when I am uploading my logo file to the site root, it simply says no permission and it doesn't upload. Any idea why this is?

Question 2: In the middle of my home page I am looking to have two modules side by side, but when I drag a module it only wants me to have the second one either under or above the previous one, is there a way to have it on the side? And not like in the sidebar. I have seen some website builders with a feature to allow side by side modules, but I couldn't seem to find any on here.

Question 3: I added a search box on my homepage, and I would like the search button at the bottom to be aligned to the left, but it stays central no matter what I try. Any idea how to fix this?

For reference, this is the site:

Any help would be much appreciated, thanks!
