We have a Drupal site rolled out on Apache 2.0.63, PHP 5.2.5, and MySQL 5.0.92. We have a section of our site called "online", which resolves fromt the url /online. Randomly, it seems, an empty folder will be created in our public_html folder called "online", and the /online section of the site will go down. Once we rename or remove the "online" folder, the /online section comes back up. None of us are school enough in Apache to know what is happening. Any ideas are appreciated!
