Hello,
I just noticed that in frontend > profile page
the link the left sidebar do not load anything anymore

In Firefox console I see this error (not sure if it is related at all with the issue)

registerEventsMessage called ial.js:3277:17
L’utilizzo di Mutation Events è deprecato. Al suo posto utilizzare MutationObserver. main.js:1:23375
ready: before call parse for last time
Object { timer: null, count: 0, error: true, data: null, parsedOnReady: false, readyEventTriggered: true, locationUrl: "" }

I tried clearing the Joomla cache but it doesn't solve the issue.
I have also tried to disable the system plugin "jQuery Easy", still no luck.

Thank you
