I'm not sure where to post this as I don't know what the problem really is. I read another post with similar issues, but I didn't understand their solution.
I bought a domain and deluxe hosting from GoDaddy. I got one site up and working (Main domain), but our company wants another site and I figured it should be simple to just upload another domain using the same hosting package. I made an AddOn Domain on my main hosting and everything was going well. Then I installed Wordpress and the new site worked fine, but my old site (which I did weeks of work on) disappeared. White screen (but my favicon still appears sometimes) of death. I am completely new at this so could someone tell me, please, what I am doing wrong? I uninstall Wordpress and my other site pops up after a bit.
