I cant access my PRTG from the web browser. When I check the PRTG service, the PRTG Core Server Service is turned off. But when I try to turn it on, the service cannot start. I go to PRTG Server Administration > Service control > start the service and it says "Could not start webserver for http://10.80.254.253:8787: Could not load "basenode : " is not a valid integer"
Can someone help me to fix this problem?
