I have a page on my site at mysite.com/publish. This page leads to a members area where they can add/edit posts from the front end. For some reason, randomly as far as I can tell, Wordpress keeps adding an empty folder to the same folder that Wordpress is in. For instance, my WP install is in a sub-directory called wordpress-2013 which is inside my main public directory. Inside that main directory an empty directory called "Publish" keeps being created so when someone tries to visit mysite.com/publish an error is given because of that folder.
I'm not sure where to even start figuring out what might be wrong. Anyone have any ideas? I found a couple threads on here from about 4 years ago that either didn't have answers or did not apply to the current WP version.
Thanks in advance.
