I'm having real problems with this version of WordPress. The neither visual nor html editors are working properly. The visual editor has no toolbar and the text is html and in a white font. The html editor has a tab but is not available. I've done a lot of research and found various suggestions on this one. I've reinstalled it at least twice. I've cleared the cache. I've checked with my host that there's no problem with Java. I've disabled plugins (there were none installed) and I've installed 'use Google Libraries'. I've tried accessing the dashboard on a PC as well as my Mac but to no avail. Suggestions on how to fix this would be welcome.
