foundry error, component not respond anymore

hi!
without any modification of my knowledge, the easydiscuss component started to block completely any function following the script error:
"Uncaught NotFoundError: An attempt was made to reference a Node in a context where it does not exist. foundry.js:4
e.script.e.extend.insert foundry.js:4
e.script.e.extend.load foundry.js:4

e.script.t foundry.js:4
(anonymous function) foundry.js:5
e.require.addLoader.e.extend.load foundry.js:5

"

please, do you have any ideas about what could have happened?
thanks in advance
