cconstantine on "[Plugin: Yet Another Related Posts Plugin (YARPP)] YARPP claims wrong text engine on posts table, but engine IS correct"

I'm not sure when this started happening.

My "consider titles" and "consider bodies" options are disabled in the YARPP options page.

YARPP says, in the message at the top:

YARPP's "consider titles" and "consider bodies" relatedness criteria require your abcdefgh_posts table to use the MyISAM enginefulltext indexing feature. Unfortunately your table seems to be using the 1 engine. Because fulltext indexing is not supported by your current table engine, these two options have been disabled.

Note that my posts table has a random string prefix as part of a security plugin by iThemes. It's not actually, "abcdefgh".

Note also that YARPP thinkg the current text engine is, literally, "1". (read above carefully, I copied and pasted).

I used a MySQL admin plugin to look at the table. it is, in fact, using the 'MyISAM" engine. Running the suggested (by YARPP) command to change the text engine doesn't change anything, as is expected if the engine is already MyISAM.

Looking in yarpp_myisam_notice.php I see these lines which seem to trigger the detection "the posts table is not using the MyISAM engine"

$table_type = $yarpp->diagnostic_myisam_posts();
if ((bool) $table_type !== true) $yarpp->disable_fulltext();

diagnostic_myisam_posts() in the YARPP core class definition however, uses a "show table status like '<poststable>'" SQL statement. When I run that statement manually, I get a row results that lists the engine is "MyISAM". So I'm thinking it's this bit of code in the diagnostic_...() core method of YARPP that isn't partsing the retued array correctly?

public function diagnostic_myisam_posts() { global $wpdb; $tables = $wpdb->get_results("show table status like '{$wpdb->posts}'"); foreach ($tables as $table) { if ($table->Engine === 'MyISAM'){ retu true; } else { retu $table->Engine; } } retu 'UNKNOWN'; }

uh, help? :D
