I use managewp which has an uptime monitor (using http://www.uptimerobot.com API) that access my site every 5 mins. My security log is full of entries like this:
>>>>>>>>>>> 403 Error Logged - January 24, 2013 - 2:11 pm <<<<<<<<<<<
Host Name: 188.8.131.52-static.reverse.softlayer.com
HTTP_USER_AGENT: Mozilla/5.0+(compatible; UptimeRobot/1.0; http://www.uptimerobot.com/)
Is there a way to whitelist the IP or anything that would permit the monitor to function correctly?
