Scheduled WordPress posts missing the schedule has been an ongoing problem for some users since WordPress 2.5. There isn’t a single solution although I did find a possible one for people using WordPress 2.6 and IIS servers.
Before I continue, I have a confession to make. I haven’t yet upgraded this site to 2.8+. I was waiting for the security updates and we’ve had two so far and I am so busy upgrading other sites that I keep putting mine off. So, I decided to wipe out the installation on my test server, make it exactly the same as this site, and upgrade everything there before upgrading here.
And I’m getting the Missed Schedule error on my test server now. Normally I wouldn’t have known this because I don’t schedule posts on the test server but when I imported the database from here to there was a scheduled post in it. I also don’t know if scheduled posts EVER worked on the test server. But it is on the same webhost. There are, however, a couple of differences such as it’s private and password protected. (And if it’s the same host and it did work before 2.8.2 wouldn’t that be a WordPress issue rather than an issue with my host? Just sayin’ – the webhost is frequently blamed.)
So, I’ve more hesitant to upgrade now because I schedule ALL of my posts – often a week in advance – more if I’m going to on vacation or especially busy. I will probably upgrade, test scheduled posts, and downgrade immediately if they don’t work. Then I will continue working on the problem on my test server rather than on my live site.
Ok – now to the point if this article. There is a plugin called Scheduled M.I.As that will search for posts marked as Missed Schedule every 15 minutes and will publish any that it finds. I tried it out on my test site and it worked great – it published all of them. (Maybe Stratos can stop by and tell us about the overhead of the plugin.)
There are, however, a couple of issues or things to know about this plugin.
- The author makes you register with his blog for you to download it. Ok, whatever, he wrote the plugin. But in my contrary way that makes me less likely to be super supportive and actually inspires me to immediately unsubscribe once I have the plugin. But I needed it and wanted to test it. so I registered.
- Once you register, confirm your email, blah blah blah, you are not presented with a neat zip file to download. Instead you are shown a bunch of code. I know a lot of users aren’t going to know what to do with this – I was even unsure what to name it.
- Copy the code and then paste it into a text editor like Notepad. Don’t use Word. Use a text editor.
- Save the files as mias.php or scheduled_mias.php. I discovered it doesn’t really matter what you name it but it does have to be .php and it should be named something that tells you what plugin the file is for.
- Upload it to your wp-content/plugins directory
- Activate it.
- If you have posts marked Missed Schedule they should be published in a couple of minutes. If you schedule one after installing the plugin and it misses the schedule, it should be published within 15 minutes.
Keep your fingers crossed that I don’t end up having this problem on my live site. I certainly don’t want to depend on a plugin to schedule my posts but it’s better than not being able to schedule them. I suppose if I DO have the problem, I can view it as a new research and learning opportunity.
