Problem...

I have installed Hot Joomla Carroussel Pro for images and I have an error message
Notice: Undefined variable: infinite_list in /home/www/etc.. (the images folder)

I have made an installation with Hot Joomla Carroussel and I don't have any problem

If somebody as a solution, il will be great !

It can be two things , first more common that images folder is not readable , check chmod of images folder (try to set it to 777 although you can leave lower permissions like 655 ).
Second it can be due some parameter not in expected scope for example if number is expected and you provide text , common mistake is something like 200px instead of just 200.

Thanks for the quick answer
I will check the fist point
But what surprised me is the fact than every things is OK with the same folder and Hot Joomla Caroussel (free edition)
