WHP Hide Posts Query Causing Server Crash

Hi

All of a sudden we have started having issues with this plugin.

We are on version 1.1.

Categories pages are having load times of beyond 40 seconds and sometimes cause the entire server to crash.

The issue seems to be related to this query:

SELECT SQL_CALC_FOUND_ROWS wp_posts.ID
FROM wp_posts
LEFT JOIN wp_term_relationships
ON (wp_posts.ID = wp_term_relationships.object_id)
LEFT JOIN wp_postmeta
ON ( wp_posts.ID = wp_postmeta.post_id
AND wp_postmeta.meta_key = '_whp_hide_on_categories' )
WHERE 1=1
AND ( wp_term_relationships.term_taxonomy_id IN (332) )
AND ( wp_postmeta.post_id IS NULL )
AND ((wp_posts.post_type = 'post'
AND (wp_posts.post_status = 'publish'
OR wp_posts.post_status = 'private')))
GROUP BY wp_posts.ID
ORDER BY wp_posts.post_date DESC
LIMIT 0, 10

With the plugin disabled the below query completes in 0.05s:

SELECT SQL_CALC_FOUND_ROWS wp_posts.ID
FROM wp_posts
LEFT JOIN wp_term_relationships
ON (wp_posts.ID = wp_term_relationships.object_id)
WHERE 1=1
AND ( wp_term_relationships.term_taxonomy_id IN (332) )
AND ((wp_posts.post_type = 'post'
AND (wp_posts.post_status = 'publish'
OR wp_posts.post_status = 'private')))
GROUP BY wp_posts.ID
ORDER BY wp_posts.post_date DESC
LIMIT 0, 10

Ideally we need to keep the plugin but cannot have the site down.
