When the WordPress Similar Posts Plugin Attacks!

Similar Posts screen snippet

Okay, so I ran into a problem recently with the Similar Posts plugin that Rob Marsh put together. I guess he’s AWOL due to health-related issues per his blog and I hope he’s just not blogging as opposed to, you know, actually quite ill or something.

Similar Posts is the best plugin I’ve found for providing…well, what the title says: Similar Posts. Putting those related posts down at the bottom of each of my posts, both so you can find something else to read and also because it provides nice links back to other parts of the blog for search engines. Every other one I’ve tried just hogs the CPU every single time you turn around. But Similar Posts, with its caching bit, works fine.

However, I ran into the dreaded “None Found” issue recently. By that I mean it was working one minute–and without me touching a setting–suddenly it couldn’t find anything to be like anything else. Now I’ve done tech support. And I know the skepticism that every “I didn’t change anything” brings on. But seriously: I’m a firm believer. If it’s working, don’t screw with it. I hadn’t gone into my Similar Posts settings in months.

I’m not sure if I just hit some threshold of post quantity or what, but it just quit on me. I could go into the database, see that all the information the plugin required was there, but still: nothing. I tinkered around with the settings for a bit but finally gave up when I couldn’t seem to make any changes to my situation at all. Then, when I found that Similar Posts was still the best one of these plugins out there, I resolved to make the damn thing work. Especially after I saw one post, inexplicably, got related posts listed at the bottom when 95% the site was doing without.

All of that to come to this point: if you’re having this problem, give these settings a try. After at least an hour of straight-up futzing around, I found these work. If you’ve got a large blog and are getting the None Found Issue, check this out. Click each thumbnail to embiggen.

General Settings:

Similar Posts: General Settings

I don’t think Output or Placement really matters in this regard. And Filter I just have some categories (namely our Contests) removed.

Other Settings:

Similar Posts: Other Settings

Under Manage Index, Handle extended characters = No; Treat as Chinese, Korean, or Japanese? = No; Treat Related Word Variations = Fuzzily; Batch size = 100.

After many, many variations on this, this one config is the one that started my Similar Posts plugin magically working again. Hope that helps you out. Good luck.

    The problem is the index of table wp-similar-post is broken. So, you can try to Recreate the index using Settings page > Similar Post > Manage the index > then hit Recreate Index button.

    Info: Actually no…if that was the problem, then recreating the index in theory should have fixed it. But trying that had no effect. Doing this did. But thanks for the comment.

    Recreate the index works fine for me! Thanks.

    Glad to hear it, Daniel. But it didn’t for me and this did. So. YMMV.
