When I upgraded my Discourse instance to 3.1.3 yesterday, I also upgraded the `discourse-solved` plugin, to this version:

[https://github.com/discourse/discourse-solved/commit/6239acdb9585f21eecfbaeda4c264997ff80cb7b](https://github.com/discourse/discourse-solved/commit/6239acdb9585f21eecfbaeda4c264997ff80cb7b)

Upon restarting Discourse, I was greeted with a non-working site with failures that I could not make heads or tails of. Firefox reported `NS_BINDING_ABORTED` errors for essentially all HTTP requests, and only the “categories” and “tags” boxes were shown. The site was consuming 100% CPU, and on Chrome, memory usage spiralled so quickly that it nearly took out my machine. With time, and because [this post](https://meta.discourse.org/t/set-slow-mode-return-a-403-error-i-am-administrator/283241) implicated plugins, I eventually discovered that reverting `discourse-solved` to this version:

[https://github.com/discourse/discourse-solved/commit/b269689ddf0e73b22a84c4f4b0227863be296b96](https://github.com/discourse/discourse-solved/commit/b269689ddf0e73b22a84c4f4b0227863be296b96)

returned my site to working order.

We need more info here, can you look at `/logs` on your site, and provide us with some error logs during the time this was an issue?
