I had the same problem, but I found solution!
This is how I did:
1. Go to: /wp-content/plugins/fancier-author-box
2. Modify line 143 in file ts-fab.php:
`add_filter( ‘the_content’, ‘ts_fab_add_author_box’);
by adding “,0” (without quotes) right after ‘ts_fab_add_author_box’
3. Result should look like this: add_filter( ‘the_content’, ‘ts_fab_add_author_box’, 0 );
This modification gives highest priority to author box and it will be loaded first! ??
