Ran into a weird issue with this plugin today. I was trying out the benchmark feature and thought enabling it to run monthly might give me some interesting data. But after checking the box and pressing save the plugin page suddenly became empty on only showed the dashboard button on the left top. The main unraid dashboard page also no longer loaded.
After uninstalling the plugin I was once more able to open the unraid dashboard page. Reinstalling the plugin instantly brought back the issue sadly. But I was able to restore plugin functionality by deleting the settings.json file in "\flash\config\plugins\disklocation". Thought i'd post this here in case this bug was unknown.
