Failed to load resource

[yadamp]

Hi All,

I'm using Seo Panel Version 3.6.0.
Four days ago, i saw my web become blank page without any errors.
I've tried using debug mode, but it's still not working.

So i use console report from my browser, then i got message of this
"Failed to load resource: the server responded with a status of 500 (Internal Server Error)"

Any one can help me to solve this problem?

Thank you,
Adam
