I inherited a site running craft and I was asked to move it to my server to host it. The other developer zipped the files and made a database dump for me.
Usually, when I move a site, they have Cpanel access, so I just move and it works with a few tweaks, but they didn't have Cpanel and I am in over my head.
I Know I haven't provided a lot to go on, as I don't know what you need to help me. What is a common thing overlooked? I can post error messages if it helps. The main one I get is the following:
