[Solved] Mod Gk News troubles with Firefox

hello the forum,
it would be nice if someone could give me a helping hand to solve this small problem, I will explain,
at first I should mention that I work locally with xampp, and the troubles concern only Firefox 3.6.8, no troubles with IE 8,
I installed the full version of The World News (gk_twn_quickstart_J!15), and then I updated joomla (1.5.15 to 1.5.20), and everything works normally both with IE 8 and Firefox 3.6.8,
but when I install Joomla 1.5.20, which I downloaded from the site joomla.org, and adds to it the The World News template (gk_twn_J!15), then there GK news module (mod_gk_news) displays the following errors with Firefox 3.6.8 (not with IE 8) :

- warning: Invalid argument supplied for foreach() in C:xampphtdocssitenamemodulesmod_gk_newshelpersdb.helper.php on line 382
- warning: Invalid argument supplied for foreach() in C:xampphtdocssitename modulesmod_gk_newstmpldefault.php on line 19
- warning: Invalid argument supplied for foreach() in C:xampphtdocssitename modulesmod_gk_newstmpldefault.php on line 31

my level in webmastering is fairly modest, so I do not understand this difference, are there changes to make somewhere ?
note : I use GK versions that I downloaded last week on the site, assuming that everything is updated, so I have not done anything special in that sense,
I do not want to cause to you additional concerns, you have already enough as it, these troubles are not very important to me,
I can very well use the full version of The World News (gk_twn_quickstart_J!15 with joomla updated 1.5.15 to 1.5.20), without having to use Joomla 1.5.20 (downloaded from joomla.org) added the The World News template (gk_twn_J!15),
cordially, Bingham

Hi

That's not the error You should worry about. Please just set the level of error showing to none at Joomla Panel global configuration for server.

thank you my dear
