Error while editing news

[Sharemmo 1]

I have updated to version 11.3 to 12.0 but it is wrong to edit the article when you go to it will be this error.

 

How can I fix it, and when viewing posts it will not increase the number of views

 

I know this part involved sql dle_post_extras how to fix it.
If you do not have a solution then you guide to upgrade all dle v11.3 source code to v12.0 no loss of data when upgrading.

You have not only updated. You have delete table ovl_post_extras from your MySQL database. Upgrade do not remove this table. You did it yourself. Now you should restore backup db.
