Warnings (illegal string offset in vr-frases-functions.php)

Welcome back! After this new release (upgrade) maybe you take a look to warnings that appear for a long time in Manage Quotes admin screen:
Warning: Illegal string offset ‘aut’ in /home3/danca/public_html/wp-content/plugins/vr-frases/includes/vr-frases-functions.php on line 35
and
Warning: Illegal string offset ‘autor’ in /home3/danca/public_html/wp-content/plugins/vr-frases/includes/vr-frases-functions.php on line 39
Thanks.
