I noticed a lot of these in the log; the site does seem to work otherwise though. Should I be worried? This is on 1.3.2.

This seems to have been caused by [trying to use the solved plugin 1.3.2](https://meta.discourse.org/t/solved-button-plugin/28129/55) - I don’t see these in the log any more after re-bootstrapping without that plugin.
