I'm completely new to this, so I apologize in advance for any obvious or stupid seeming questions.
This is a new install, so I have NO posts or any other files at all. I realized quickly after I installed that I wanted or needed multi site for the application I have in mind so tried to read how to convert. Info I read said I needed to make changes to wp-congig-php and .htaccess. Added the code i was advised to add to the wp-config-php, but .ht access was empty. I was told by the support team at A Small Orange to try changing my permissions then changing back in order to re-populate that .htaccess file. Tried that and did something wrong I guess. Now my site is a blank white page, and in my dashboard it says no themes exist. When I try to install a new copy of the theme I chose (iRibbon) it starts downloading and unpacking the pkg then says it can't create a directory.
I also tried to access stuff through WinSCP (which I don't really understand)but don't think I was ever able to even login other than anonymously so I don't know if it's possible I changed something there.
Any help at all would be appreciated. Spent all day yesterday trying to change to multisite only to make the site completely inaccessible today
