Easyphp comes with some predefined global alias - "/home", "/modules" and so on. This is a problem if you install software (in the root of a virtual host) that contains directories with these names. An example:
1) Create virtualhost drupal.local and point it to a Drupal directory/installation (using "Virtual Hosts Manager").
2) Visit drupal.local/modules. The Easyphp modules are listed in stead of the contents of the Drupal modules directory. (This of course breaks Drupal.)
I suggest changing these aliases to "/easyphp/home" and "/easyphp/modules" and so.
