I’m experiencing a very strange problem.
I have a WordPress site installed in a /wp directory, but the site address is set to the root domain. Within this installation there is a page called store, which sits at /store (due to the site address setup within WP).
However, a couple of times now, a new folder called /store has been created in the root directory. I’m the only one with FTP access and I have not created this folder.
Does anyone have any ideas how this could be happening? I’ve never seen anything like this before. Could it be generated by a plugin? A permalink issue? It doesn’t sound likely to me, but those are the only explanations I can think of.
The site in question is hillaryreynoldsband.com.
Posting my comment as an answer in case anyone else encounters the same issue
An old or incorrectly configured sub-domain can cause seemingly random folders to be created in the WordPress directory, usually removing or re-configuring the sub-domain will fix the issue.
