My site started doing it after only 6 posts. So I don’t think it’s some kind of limit on the free version. Suspect it’s just a bug.
Well I seem to have found a fix that works. I just de-activated and re-activated the plugin. I didn’t lose any posts or any subscribers in doing this process, and it magically reset all the queued posts to 15 minutes.
If you want to try this, go to Plugins -> Installed Plugins on the main menu, and then under WP Easy Post Mailer, click on the Deactivate link. Then click on the Activate link.
Hope this works for you!
No I didn’t get an answer – it would have been posted in this thread. I’m going to try uninstalling and re-installing the plug in to see if this helps.
