I no longer had access to my book list in the administrator, so I put as before.
An error message appeared. I saw no longer the element author on my site in the description of a book.
This problem is strange ...
How to solve it?

Problem solved

"components/com_abook/models/author.php, line 60 replace all the  "jos_" to "#__" :

function _buildQuery()

{
                $where          = $this->_buildContentWhere();
                $orderby        = $this->_buildContentOrderBy();

$query = "SELECT book.*, "

. ' CASE WHEN CHAR_LENGTH(book.alias) THEN CONCAT_WS(\':\', book.id, book.alias) ELSE book.id END as slug, '

. ' CASE WHEN CHAR_LENGTH(cat.alias) THEN CONCAT_WS(\':\', cat.id, cat.alias) ELSE cat.id END as catslug, '

. ' ROUND( v.rating_sum / v.rating_count ) AS rating, v.rating_count '

. ' FROM jos_abbookauth AS authbook '

. ' JOIN jos_abbook AS book ON authbook.idbook=book.id '

. ' JOIN jos_abcategories AS cat ON cat.id=book.catid '

. ' JOIN jos_abauthor AS author ON author.id=authbook.idauth '

. ' LEFT JOIN #__abrating AS v ON book.id = v.book_id '

. $where

. $orderby

;

return $query;

}
 

I see the publications of each author here

However only the last books we see the various descriptions ...

Have you any idea?
