It would be at the very top of the page before any of that debug information. If it's not then your action is either being executed or isn't being executed at all entirely. Please provide a screenshots of your action configuration (all tabs).

Your action is not set to debug mode.

1. Edit your action

Action debugging is now enabled and debug output is now visible. Login and it'll tell you if access failed or if the conditional failed.

It's failing at the conditional as the strtotime isn't accepting the values. It's due to [lastvisitdate] being formatted instead of a timestamp. You'd need to also strtotime the [lastvisitdate], but a format function inside of a format function isn't supported yet so it won't work. So when implemented you'd have the below.

strtotime(+1 DAY,strtotime([lastvisitdate]))

I've added a feature ticket to implement support for this, but I've nothing else to suggest unless maybe you use a CB Query Field to handle incrementing lastvisitdate by 1 day and returning its timestamp using SQL functions then comparing against it.
