# wp_posts table engine issue

 * Hello,
    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](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…
