[Typo3] EXT: slideshow extension problems on fresh installation

["Jesús H."]

Hello list,

I've just installed the Flash SlideShow (Ext. Key: slideshow)and it's 
not showing on the FE although I can create the albums and insert the 
plugin as content at the BE.

In the FE I don't get an specific error but when I tried to see the XML 
output generated at the pageType by default 9005 (@ 
http://www.domain.com/index.php?id=2&type=9000) I got the following:

---------------------------------------------------------------------
Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL 
result resource in 
/home/httpd/vhosts/domain.com/httpdocs/t3lib/class.t3lib_db.php on line 741

Warning: Cannot modify header information - headers already sent by 
(output started at 
/home/httpd/vhosts/domain.com/httpdocs/t3lib/class.t3lib_db.php:741) in 
/home/httpd/vhosts/domain.com/httpdocs/tslib/class.tslib_fe.php on line 2612
---------------------------------------------------------------------

As I said in the FE I don't even get the flash embedding of the plugin.

My configuration is:

Typo3 3.8.0
Developer API  	api_macmade  	0.2.0
Flash SlideShow slideshow 	0.2.0

Does anybody have hint so I can continue forward and use this extension?

With best regards,

Jesús H.
