I’ve been working with a client who has created a dozen or so EE websites. I was surprised to see that he has them all installed in subfolders off a single server root. I guess he is maintaining these sites so wanted to have them all in one place. I was surprised that you could even do this without there being issues, but it appears to be working fine for him. Can you think of any reason why you wouldn’t advise this kind of installation? I’m currently having an issue with one of these sites installing the LG-htaccess-generator extension, and I didn’t have a problem installing it when it was on a stand-alone site that was installed in root.
