Website forum does not work properly in macOS Mojave Safari

  • When i wanted to post a question to the forum, I found that I cant post a new topic in Safari in macOS mojave (OS I use for internet/emails/iOS synching) as doing it in Mavericks is risky, and not all websites work in OSX Mavericks Safari.. I click NEW TOPIC in Safari on Mojave .. the button is dead... so I use windows 7 with Opera to post instead.
