Five days ago, I upgraded my website to wordpress 3.4 and also upgraded on that occasion WP Super Cache to the latest version.
I did not change any settings on WP Super Cache - I noted that preload (which I've already used prior to upgrade) had split taxonomy to a new checkbox, but I left it unchecked.
Since then, without fail, I get an email every day - and on one day even twice that day - saying "Preload may have stalled/preload has been restarted".
I have no idea what changed. I also don't know if this is something I should be concerned about? Is there anything I should look into? If it needs fixing, what do I do? If it doesn't, how do I turn those emails off?
Any advice would be appreciated.
