Can you be more specific? how do I activate? Or where do I find the option?

I am using joomla 3.6 and I can't find "Save History" that appears on step 3 of the link you sent me.

if you have saved your article with all the tabs having a problem and that you don't have any versioning activated your website, I can not do more

you should restore a backup of your website to get the previous version of your article

if you don't have the article versioning, you are probably not up to date with your joomla version

all this is out of the scope of my extensions
