mySQL errors in gallery back end

[Jangla]

Just installed the latest version of the component, the plugin and the button and slideshow plugins and am getting these errors on the images page:

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/jangla/public_html/test/libraries/joomla/database/database/mysql.php on line 344

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/jangla/public_html/test/libraries/joomla/database/database/mysql.php on line 344

Warning: Invalid argument supplied for foreach() in /home/jangla/public_html/test/administrator/components/com_phocagallery/libraries/phocagallery/render/renderadmin.php on line 65

And then this one on the Multiple Add page:

Warning: Invalid argument supplied for foreach() in /home/jangla/public_html/test/administrator/components/com_phocagallery/libraries/phocagallery/render/renderadmin.php on line 65

Should I be worried?!
