Estoy intentando crear un directorio en  una web con el componente SOBI 2, pero me da este error:
 
No valid database connection 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 '' at line 1 SQL=SELECT `parentid` from `jos_sobi2_cats_relations` WHERE `catid`=

¿a que se refiere? como podría solucionarlo?
 
Gracias
