Hi, if I clicked on “Copy to WordPress Theme” several times will this hurt anything? How would I go about un-copying it without crashing my site? Thanks for any direction you can send my way…
Not at all. But why you want to Copy that to your wordpress theme ? It is only needed when you need to modify our layout and to make it update safe.
To uncopy it, you need to delete it from the masonry-layout folder from wp-content/themes/ . You need to use FTP to do it. But even in most of the cases it is not needed.
