Problem With PHP Site Recurrent Error In Logfile
I have a tracker (CPVLab) installed on a Droplet and it appears to work fine but I have a recurrent error in the logfile:
2015/07/23 14:30:57 [error] 1302#0: *10 FastCGI sent in stderr: "PHP message: PHP Notice: Undefined variable: query in /var/www/mysite.com/htdocs/traydata.php on line 0" while reading response header from upstream, client: 176.249.72.xxx, server: mysite.com, request: "GET /traydata.php?user=xxxx21&pass=d2c5fa20f0d93ec895a521d02fbf513d&action=campaigns HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "mysite.com"
Ioncube loaders are installed and according to ioncube support, installed correctly.
Can someone suggest where to start looking for this error?
Thanks in advance.
