Everyone's been there: That nightmare client that clings to your workflow like a burr to wool pants. I've recently decided to cut mine loose, and to do so, I'm going to email the client a snapshot backup of the site. Before I do that, though, I'd like to make sure that any trace or me or my involvement is removed from the site.
I deleted all the premium plugins which are based on my API keys (eg WPMU Dashboard, WPMUDev Videos, etc). After that I used WP-Optimize to clear revisions and transient options to make sure the site is 100% WYSIWYG before passing it off to the client.
Anything I missed?
Best regards and good clients for all!
