Error in admin page

[olking]

I am getting an error message when I open the admin page http://localhost/catalog/admin/login.php

which says:

 

Warning: error_log(/var/log/www/tep/page_parse_time.log) [function.error-log]: failed to open stream: No such file or directory in C:\Program Files\xampp\htdocs\catalog2\admin\includes\classes\logger.php on line 49

Parse Time: 0.288s

 

I am not aware of whatever action produced this.

This installation is on my localhost.

I have a similar one on my remote host server which doesn't give an error.

 

The system seems to operate quite ok but an error message is a bit of a worry.

Can anyone suggest a repair please?
