loading addon domains
I have a little question about addon domains, I currently have a SEO hostgator account and have set up 5 accounts each with several addon domains, except when I try and add data to the addon domain and drop the files into the public-html folder of the addon domain, the file name cahnges to a (dot)xhtml file type and when I try and load the website in my browser I get the index of/ command and a list of all the files within the directory.
If I do the same for the main account domain, the file type remains a (dot)html file type and I do not get the index of/
Has anybody any ideas?
Kind Regards
Peter
