This question about Using an extension: Answered
I installed
MetaCommentPlugin in a new Foswiki 1.1.3 installation. The reply/edit/delete buttons for old comments did not work. The
JavaScript error message was "a.jsonRpc is not a function". It seemed that the
JsonRpcContrib JQuery plugin was not loaded, although it was installed and enabled in the
JQueryPlugin options.
First I tried to add %JQREQUIRE{"jsonrpc"}% to metacomments.tmpl, but that didn't help and it seems not to be necessary anyway (why?).
Then I upgraded
JQueryPlugin from 4.03 to 4.10 and that solved the problem.
