running ccomment core 6.0.5
Like most others I updated Joomla 3.8.13 to 3.9 on 1st November.
Thereafter when clicking in the backend to access joomla content, joomla throws and error (a.note extra column) However you can add new content and save.
I have now reverted back to the previous version of Joomla and , as before, all is ok
Can you advise is this a com_content compatibility issue or do you think its a joomla issue.
