Well, without know exactly what files were changed where this is almost impossible to answer. Things hat can see easily…

Looks like the Default Entry Card template and the Bio Entry Card template where significantly altered. You might be able to use the card-default.php and card-bio.php filers, respective, in you altered versions as template override files. I would highly recommend altering templates using that method since that makes them updates safe.

I also see the the IM options seems to be changed. You’ll have to make those changes again. Or, better yet, you can use the new cn_instant_messenger_options to add or change the values to suit. This would also make those changes update safe.

Basically, yes, if you altered any other core plugin files, you would have to apply those changes again to the new version, there’s not a way to update and keep changes to core files.

Now, to fix the visual editor in the old version … that is broke due to change WP 3.8 made (I think that was the version). I think all you need to do is make this change:

Hope that help!
