 * Hi,
    I have a problem with W3 Total Cache. I disable the plugin and then I reactivate
   it buy I receive this warning message when I try to login in the admin panel.
 * ‘Warning: require_once(/home/vkrnplca/public_html/wp-content/plugins/w3-total-
   cache/lib/W3/NewRelicService.php) [function.require-once]: failed to open stream:
   No such file or directory in /home/vkrnplca/public_html/wp-content/plugins/w3-
   total-cache/inc/define.php on line 1451
 * Fatal error: require_once() [function.require]: Failed opening required ‘/home/
   vkrnplca/public_html/wp-content/plugins/w3-total-cache/lib/W3/NewRelicService.
   php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/vkrnplca/public_html/
   wp-content/plugins/w3-total-cache/inc/define.php on line 1451′
 * I try to upload the NewRelicService.php to the folder but it disappear everytime
   that I upload it. I know that seems crazy but I’m not alone [http://wordpress.org/support/topic/newrelicservicephp-automatically-always-missing?replies=2](http://wordpress.org/support/topic/newrelicservicephp-automatically-always-missing?replies=2)
 * I know how I can disable the plugin to see the admin panel but I want go reactivate
   the plug-in.

 * same here, in italy.
 * hoping to shed some light,
 * i must admit that the file NewRelicService.php gets automatically deleted (after
   a bunch of seconds) in any folder of the server i’m putting it in.
 * just this server has some antibodies? or some paranoid settings?
 * wouldn’t you like to look at some server configuration parameter, perhaps?

 * yes, as stated in the link above, some antivirus doesn’t like this file. On my
   shared hosting, newrelicservice.php is a false positive for the server antivirus.
   So, in this case, just contact your provider and voilà, you can upload it.
