I’m not sure if I’ve misunderstood something, or there is a problem with the plugin, or something bent in discourse.
As of last night we’re on the latest version of discourse beta, and the plugin was also first added last night. It works fine, except that any query which involves the declaration of an integer (in [params]) yields: an error message indicating “Parameter declaration error - the default value is not a valid int” whenever I try to save it.
(This is the case for all the examples on What cool data explorer queries have you come up with? which I have copy/pasted from meta (yes, I retyped the [params] section manually, just in case it was some issue with copy/paste adding weird characters).
