Simply-VisiOn Theme | error: Missing required field "updated".

Hello.
I am using the wp theme Simply-VisiOn.

After doing the snippet-test I recieve the error: Missing required field “updated”.

I did plenty of research but I cannot find the codes to add UPDATED.

I checked funtions.php and many others but nowhere(!) I can’t find a “entry-date” or “post-date” where I could possibly add “updated” to get rid of the error.

As well do I have the error: Missing required hCard “author”…

I can’t find the files in Simply-VisiOn Theme.

Thanks for your help in advance!!
