    Running WP Multisite 4.5 Nginx 1.9.14.

    When I click an option I get the white page of death.

    Here is what my log says:

    2016/04/21 08:02:48 [error] 29735#29735: *1775 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Uncaught Error: Cannot use object of type WP_Error as array in /var/www/example.online/html/wp-content/plugins/debug-this/debug-this.php:195

    I found a few threads here where people had same issue but no follow up on those threads.

    Any idea what’s going on?

    Thanks for the server info and error log. I have been unable to reproduce this so far but I will re-examine that section of code when time allows.

    Hi there,

    It happens if you get a WP_Http timeout, in this case, $response[‘body’] doesn’t exists.

    An easy fix is to check if the WP_Http ran successfully or not…

    Cheers =)

    This is really old but I think the issue was the path was too long as debug bar has lots of GET params so it increased the size of the header to be more than the allowed header size. I increased header size above default in nginx and it fixed it.

    Hey,

    I don’t think so, I got this error due the WP_Http timeout. I got the error and debugged the plugin to see the output: an object (error object) instead of a response, that’s why the plugin breaks sometimes.

    Best!

    In time: the best plugin I’ve heard about! Helps a lot!

    Thanks for the tips. Version 0.5 catches the WP_Http error and display the error message so please post it here if you see it again.
