Crazy stuff.
Installed Chrome and imported bookmarks, it then installed adblock as per usual so had an idea adblock might be the reason the myBB is having issues, yes I know myBB relies on adverts to give us goodies and stay UP but I'm at work.
Openend Safari and signed into myBB and all is suddenly right as rain.
Im back on safari ,![]()
Rather use uBlock. Less memory. Way faster for to be honest.
