I've found the RFI, but when I tried to used a path with w**/********.*** I've got a 403 error.
Am I right or should I find another file ? Because I used the same path in LFI challenge, but this time I've got an error :

PHP Fatal Error(1): date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in core/inc/util/GWF_Log.php line 202
I think I have the right path, but not sure.
