Hi,

Previously, you had to include the information in functions.php file
which files were changed to turn on that change on the theme.

Documentation: https://developer.wordpress.org/themes/advanced-topics/child-themes/

Right now, you don't have to include that information, your changes will be
automatically added without leaving a note in a functions.php file - of
course,
you have to turn on the Child Theme on your website. Of course, to make
that change we had to change the structure of Child Theme a little bit.

To make your Child Theme work again, you have to find that function in your modifcation file(functions.php) and replace the 'mfn_opts_show()' to 'echo mfn_opts_get()'

After that, everything will be working fine, we had to make that change because of the new envato rules, more about it here: https://help.author.envato.com/hc/en-us/articles/360000481243#h_674316188621522302914837

Thanks

So that means I have to go through all the files of the theme and replace mfn_opts_show() with echo mfn_opts_get() correct ?

If yes, how can I easily do that instead of opening each file replacing the code, save it and re upload to server. 

Also, can you name the files I need to change the code in?

thanks

Pablo

Not in all of the files.

You need to replace mfn_opts_show() with echo mfn_opts_get()

in the functions.php file in the child theme.

I edited the message above to be more user-friendly.

Thanks
