Thread:Extension talk:CharInsert/It disappeared!

Within the last couple of days, this gadget stopped working on en.wikipedia. I've gone to my Preferences, switched off the gadget, saved, purged the cache, switched it back on, saved, and purged the cache, without success. Any idea what's wrong, or where I should report it if not here? Thanks. (Please try using D'Ranged 1 to notify me of a response; I'm not sure it works across wikis.)
