[Typo3] sg_Glossary

[Horn Gábor]

Hi,

i try to use sg_glossary, but i get the following error messages in the 
top of the page on the FE where i placed the plugins (one with code 
"search glossary" and other "list+show glossary" as teh manual described):

query 	SELECT uid,title FROM be_groups WHERE title='' ;
ERROR 	You have an error in your SQL syntax near '; ' at line 1
FILE:LINE= 
/home/elofizetok/digicam/website/typo3conf/ext/sg_zfelib/class.tx_sgzfelib.php:4420 



Can you please help me what's this or how can i fix it?

thanks, hirisov
