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?
