Just a reminder to myself that the Evergreen Post Tweeter plugin conflicted with the WordPress timer service, at least for my blog. As a symptom of this, scheduled posts wouldn’t post on the publish date and time, and there would be a backlog of actions queued up.
I was only aware of this since the UpdraftPlus backup plugin wouldn’t run its automated backups. UpdraftPlus itself would complain about incomplete actions. On a hunch, I disabled Evergreen Post Tweeter since it times the posting of old posts on Twitter. Sure enough, after disabling Evergreen Post Tweeter, WordPress started behaving normally. Scheduled posts published on cue, and I have yet to see incomplete actions reported by UpdraftPlus.
