I recently updated my Joomla installation and noticed that the installer created folder named 1new on the server. Folder contains two subfolders; tmp and logs. Logs folder contains two files joomla_update.php and error.php. Both files contains only some log information but error.php contains unsuccesfully login attempts too.
# #<?php die('Forbidden.'); ?> #Date: 2017-01-23 20:33:34 UTC #Software: Joomla Platform 13.1.0 Stable [ Curiosity ] 24-Apr-2013 00:00 GMT #Fields: datetime priority clientip category message 2017-01-23T20:33:34+00:00 INFO **.**.**.** joomlafailure Username and password do not match or you do not have an account yet.
What is the meaning of that folder and those logs?
