Count wrong on Content Audit Attributes

[MortimerCat]

I just installed v2.0 from the official repository. The only setting I changed from default was to to set Audited content types to Posts

I made my first edit, marking a post as Audited & Trivial. All looked fine, the post list showed Audited & Trivial.

Then I went into Content Audit Attributes and noticed the wrong totals . Audited and Trivial were showing zero, but redundant and review style were showing 1.

I found the bug in the function content_audit_term_count() in taxonomy.php

// update per-post-type count                                
if ( isset( $typecount ) ) {                                        
     $option[$term] = $typecount;                                        
     update_option( '_audit_term_count_'.$post_type, $option );                                
}

$term is derived from the field term_taxonomy_id but the $option array is based on term_id.

This has only manifested itself in my system because at some point over the years my term_taxonomy table has gone out of sync with my terms table. I am not familiar with these tables, but it looks like that most of the time the ID fields in the term_taxonomy table match. My table IDs are out by one.

term_taxonomy_id      term_id                taxonomy  description    parent     count
16843                  16844                content_audit               0          3

I believe that most people would be getting the right value for $option purely by chance.

I could not see a quick general fix so I have done a kludge fix to my system by adding 1 to $term (my esoteric way of converting term_taxonomy_id to term_id). My system now shows the correct totals.

$option[$term + 1] = $typecount;
