For some reason, one of my top posts as reported by WordPress Stats is actually non-existent...

What I see is:

#2147483647 (loading title)

and it links to "...?p=2147483647" which returns a 404.

Now a bit of background info:

  • I'm actually using the following permalink settings: /%category%/%postname%/
  • Stats for other posts seem to be fine
  • I migrated from tumblr to WordPress

The odd thing is looking into the database where the posts are stored I can not find any reference to that particular ID.

Also, I appear to have several 'duplicates' of posts in the database - the difference being in a couple of fields (I'm guessing versioning or something?)

I've googled a bit, and the closest I've seem to come is: http://wordpress.org/support/topic/solution-for-id-loading-title-coming-back-from-stats_get_csv-function

However, that seems to assume that the ID actually exists, but WordPress/WordPressStats is just for some reason unable to get the title.

So does anyone know why WordPress Stats is listing this non-existent page? (It comes #2 in all time top posts!)


  • I guess the problem came with the migration which failed in some point (How many posts have you got? - 2.147.483.647 is quite a high number). The "dublicates" you're talking about maybe post revisions. – kaiser Jun 19 '11 at 13:51
  • Not many posts at all, in fact 9 all up. First post has ID of: 2142165720, and most recent post has ID of: 2165214978. I think these IDs are taken from tumblr IDs. I've checked tumblr too - no posts that correspond to that ID! – pyko Jun 19 '11 at 14:21
  • What version of Wordpress are you using? and What version of Wordpress Stats are you using? – Hameedullah Khan Jul 1 '11 at 4:57
  • I'm using WordPress 3.1.3 and WordPress Stats 1.8.1. I have another blog using the same combination and has no problems. – pyko Jul 1 '11 at 5:20

    2147483647 = 2^31 - 1. I suspect you hit a counting bug somewhere. – Otto Jul 2 '11 at 15:37

Turns out WordPress doesn't deal well with post IDs > 2^31.


Tumblr in particular has post IDs greater than this, so it's not recommended to keep old post IDs from Tumblr on an import.


After Otto's awesome observation, some SQL trickery I believe I have now fixed the problem :)

The Problem

I was using tumblr and transferred my posts to WordPress. However, since approx mid-Dec tumblr postIDs were greater than 32-bit MAX_INT (2147483647). Of course, I had several posts created after mid-Dec, thus they all had postIDs greater than MAX_INT - http://wordpress.org/support/topic/plugin-wordpress-importer-importer-fails-for-post_ids-over-php_int_max-of-2147483647

For whatever reason, my posts imported fine, however the WordPress Stats did not like these insanely large numbered postIDs, thus I experienced the problem outlined in my question.

The Fix


Fiddling around with postIDs/database can potentially screw up your blog - linking etc. So perform at your own risk!

I was very lucky that this was a fairly new blog - 0 comments and only 18 posts... so overall it was still fairly simple.

Remember to back up, incase something horrible goes wrong!

To solve this problem, I backed up WordPress, cleaned up my WordPress database, exported all tables that had references to postIDs, reduced the postID values, reset the auto-increment value, re-inserted the data.

Backing up: I did an XML export and also performed a full backup of the blog via cPanel.

Cleanup database: There was a useless rows (for post revisions) in the database, so to simplify the later steps I first cleaned up my database using the following plugin: http://wordpress.org/extend/plugins/wp-cleanup/

Export tables: Going into phpAdmin through cPanel, I went through each table and any that had references to postIDs I exported into a .sql file, remember to include the drop tables if exists option. The tables I ended up needing to export were: wp_posts, wp_postmeta, wp_term_relationships. !!! NOTE: I was lucky that this is a relatively new blog. So there were 0 comments, thus did not need to worry about comments!!!

Reducing postIDs: Using numbers (ie. excel) I first made a mapping of the old/new postIDs. (eg: 2165214909->3, 2165214895->4 etc). With the old/new postIDs 'set', I went through each of the exported .sql files and did find/replace all. Note: it appears that attachments in posts also have their own postID so it can be a tad confusing

Reset auto-increment number: In the wp_post.sql file, I reset the auto-increment value to something like 30. That way the next blog will have a postID starting at 30. If you don't reset this, any new posts created will still have high postIDs and you'll be faced with the same problem.

Re-inserting data: Back in phpAdmin, using the .sql files containing the new postIDs I imported the data back in. Since in the export I chose to drop table if it exists, it cleared the existing tables and inserted with the "new" data.

After doing all of this, I did a quick sanity check to make sure everything was fine. Public blog - clicked around, made sure images were there, searching works, tags worked etc. Admin section - check that when you hover over 'Edit' it shows the correct new postID, creating a new post uses the new auto-increment id, and of course (after a few days) that the WordPress stats was back to normal.

All checks passed, so I think the fix has worked :)
