[zenner]

Hi! Please help me with my problem! I can't install fonts in Phoca Font, the error is:
Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in /var/www/vhosts/galbur.pro.md/public_html/libraries/joomla/database/database/mysql.php on line 344

Can You help me to resolve this error?
Thank You!!!
