I really like this mod, but I've run into just a couple of issues (with the newest release candidate). I've included screenshots.
First, I am getting an SQL error while I was trying to delete a couple of test articles. The error reads:
SQL ERROR [ mysqli ]
Out of range value adjusted for column 'cat_articles' at row 1 
UPDATE phpbb_article_cats SET cat_articles = cat_articles - 1 WHERE cat_id = 1
Though the error does come up whenever deleting an article, the article does delete.
Next: While setting the group permissions, I noticed that this mod has funkified the headings of the other areas in which group permissions can be set. View this Screenshot
to see what it's done.
Post Bot Plugin
: After an article has been submitted and the post bot plugin posts the announcement in the forum it's suppose to, the board index does not show that there is a new post. Screenshot
of board index.
: After removing an article from the knowledge base, the latest articles still shows the titles of the deleted articles. Screenshot
Though there are two articles in the knowledge base, the KB index page does not indicate there are any articles at all. Screenshot
And finally, while adding a new article, a new SQL error has cropped up.
SQL ERROR [ mysqli ]
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE user_id = 2' at line 1 
UPDATE phpbb_users SET user_lastpost_time = 1258139066, user_posts = user_posts + 1, user_words = user_words + WHERE user_id = 2
I do have a feeling that the Word Count mod is the culprit contributing to the SQL errors, though I am not sure.
And -- If I access the Mod CP from the board index, I see the tab to moderate the KB. I was wondering, though, if the link to the Mod CP is also suppose to be accessible from the KB index page as well? Screenshot
Also, there is a file missing:
template->_tpl_load_file(): File ./styles/fae_forest/template/kb/mcp_kb_kb_main.html does not exist or is empty
Though I am not using prosilver, I have checked the styles/prosilver/kb/ folder in the download and the mcp_kb_kb_main.html file isn't in there.
