Hi Guys,
I have just installed LibreNMS to monitor our network devices however, I am seeing an error on the real-time graph page.
I am currently using Chrome
I have tried to use Firefox but the real-time graph page only shows blank without any error messages.
Your thoughts would be much appreciated.
If you need anything, feel free to ask. Thank you.
Hello,
run ./validate.php and pastebin the output.
I had the same thing, it was down to my nginx config.
Do you have anything like this in your nginx config file:
add_header X-Frame-Options DENY;
Can you open the page in Chrome and then hit F12, what errors are in the console?
Hi Everyone,
I have solved this issue with tslytsly suggestion.
I have found that X-Frame-Options has been set to Deny. Iām using Apache2 as my web server.
Thanks for all the help.
Good stuff.
