getting error on line 158 - urgent solution needed

hello

i have installed hot carousel pro module

but it gives this error

Warning: Invalid argument supplied for foreach() in /home/larslilholtband/domains/horningfloor.dk/public_html/modules/mod_hot_joomla_carousel_pro/mod_hot_joomla_carousel_pro.php on line 158

can i know plz why it happens and what i should do to rectify it ?

urgent one

waiting for reply

It's not an error it's a warning.
Try to set Error Reporting (Global Configuration > Server Setting > Error Reporting)to 'Simple' or 'None'

Would this have anything to do with the image links problem?
