[resolved] wp_posts table engine issue (10 posts)

    I recently moved a dev site from an IIS server (don't ask) to a proper Apache server. Naturally I had the InnoDB error, so I changed all of the tables to MyISAM, but YARPP is still not working perfectly. Now I have the error:

    YARPP's "consider titles" and "consider bodies" relatedness criteria require your hmp_posts table to use the MyISAM storage engine, but the table seems to be using the 1 engine. These two options have been disabled.

    Not sure what the "1" engine is!

    Curiously I have a terrible hack working... if I inspect element on the Consider Titles and Consider Bodies fields, remove the Read Only / Disabled restrictions and choose these, then save - it works. But if I want to change any other settings I have to do this hack every time! haha.

    Any idea what needs to be done here?

    I have removed the two YARPP tables, and reinstalled the plugin, and have run http://mitcho.com/code/yarpp/sql.php but I still get the "1 engine" error as above. Another symptom is that my hack doesn't let the custom PHP template I made work!

    Any ideas? About to throw in the towel and try to find another related post plugin that allows for custom templates!

    How does one totally uninstall YARPP? Maybe I didn't do that right?

    Hmm, since you're on LAMP now, I assume this is a MySQL server?

    What version of YARPP are you using?

    One thing you might want to try is to completely reset YARPP's settings. In the wp_options table, find the options containing the word "yarpp" and delete them.

    Boom! Yeah, that was it. Once I deleted the entries in wp_options as well and reactivated the plugin the problem was solved.

    I vote you make the uninstall process a FAQ.

    Thanks for the support!

    Glad that worked. Sorry that happened in the first place, though. I'll look into it.

    Before you start troubleshooting migration from IIS I'm sure there are lots of better things WordPress devs can do. Like smell a flower, or alphabetize the contents of their fridge!

    Thanks for your awesome dedication!

    Same here. And I followed your instruction, but it didn't work. Then I realized I didn't deactivate some cache stuff. Right after turning them off, Boom <3

    Thanks both of you!

    I recently had to rebuild my wp_posts table and ran into the MyISAM storage engine issue. Uninstalling, deleting YARPP wp_options entries and reinstalling did the trick. Straight life savers, thank y'all!

    For google'ers,

    If you're running memcached or apc you'll need to find and delete the database tables via mysql using the following (or similar command):

    SELECT * FROM wp_options WHERE option_name LIKE "yarpp%";

    delete all you find.

    Then restart the services:

    sudo service memcached restart && sudo service php5-fpm restart && sudo service mysql restart

    Thanks for this post, I hope this helps some of you out there...
