Okay, so here is my problem. I have a wordpress installation at _________.com and a sub-directory installation at _______.com/2015. When I try to go to ______.com/2015 directly, I end up at the homepage for _______.com.
When I go to /2015/wp-admin/ and log in, I can then access it directly, but the homepage of that subdirectory installation is not accessible by the public.
Could this be a caching problem (if there was previously a /2015/ page or something)?
