Have you tried updating you website to WP 4.2.2 and it just won’t update?
Well you are not alone! It seems that Wp 4.2.2 is tempermental and wants to be a diva, so here is the secret to getting your WP install to update: Deactivate all of your plugins! Yup, this should allow you to update to WP 4.2.2 without any issues. I recommend reactivating your plugins ONE-by-ONE so if there are any conflicts, you will know what plugin is problematic and where to start with trouble shooting the issue.
