Not certain if you figured this out, but for any others that land here related to this error:
Make sure to go to your WordPress Dashboard > Settings > Permalinks and click Save Changes at the bottom of the Permalinks screen after you install and activate the plugin.
Xaymar,
Adding ?$args at the end of my try_files for /index.php
resolved this issue for me.
try_files $uri $uri/ /index.php?$args;
nginx 1.12.0, PHP7, wordpress 4.7.4
Changing line 291 worked for me on Top 10 v2.4.2, WordPress 4.7.3, PHP 7.1.2.
This resolved an admin dashboard left panel submenu popout on hover issue I was experiencing also.
This resolved the Top 10 widget in (any of) my sidebars stopping output of the rest of my widgets. Sidebar was blank if I tried to load this widget.
