Can't reply to my discussions
I have posted a discussion and now I cannot reply to it.
Every time I write a reply to another User and click Reply I get a red notification saying:
"Your post could not be saved. Please try again in a few moments. Click here to refresh this page."
I've tried signing out and back in, restarted my Mac, tried posting in Safari and on Windows Internet Explorer but it's the same thing all the time.
Funny thing is, the content does get saved normally. It just doesn't get posted and when I come back to the discussion and want to post a Reply, it asks me if I want to Reload my comment that got saved.
If I click to Refresh the page I get this page:
MacBook Air, OS X El Capitan (10.11.6)
