I searched and found and old but relevant post on this subject and replied to that post, but I'm starting a new thread here with the same issue:
Hi,
I found this thread and hoped it would help me, but it didn't.
I attempted to install WordPress in a subdirectory, but I apparently messed that up and installed (via the Installatron) it in /www. Otherwise the install went well and I was able to access WordPress.
Unfortunately, I have non-WordPress files on /www and I lost access to these. When I try to go to
www.treatcfsfm.org I do not get my site, instead I get "Error: Could not connect to the server."
So I uninstalled WordPress, using the Installatron, and deleted the .htaccess file and the WP database, but still get the same error.
Any ideas on getting back to my former site?
