Can't update

Hi!

I’m trying to update attachments and I’m feeling a little dumb, I can’t do it =..(

When I update I loose all my pictures (all of them attached to woocommerce products) I guess that this will be fixed as soon as I’m finally able to work with all the codes and stuff and update it wright.

I allready did the migration.

The main problem starts here, when I add the attachments code (copied from adjust/attachments on WP admin) to my themes function.php the web goes blank and I can’t do anything else.
And I don’t know wich templates do I have to update.

As you can see I’m a beginner on WP, and my english ain’t awesome.

Hope you can help me. Guess I need an updating for dummies ; )

Thanks in advanced!
Paloma.
