I'm trying to post one post, but the following error appears:

Code:

Could not insert new word matches

DEBUG MODE

SQL Error : 1271 Illegal mix of collations for operation ' IN '

INSERT INTO nuke_bbsearch_wordmatch (post_id, word_id, title_match) SELECT 227956, word_id, 0 FROM nuke_bbsearch_wordlist WHERE word_text IN

Line : 252
File : functions_search.php

There is some words after the last "IN" code, but when I try to post this words here, the same bug appears.

What I need to do?
