File_put_contents() error message on top of page mobile site

Joomla 1.5.23
Installation OK.

All is well but when I try my mobile version on my Iphone I have this error message on top of page :
"file_put_contents(/home/....../images/stories/../Resized/index.html)
[]: failed to open stream : no such file or directory in on line"

Do you have any solution to this problem ?

Permissions on directories ??*

Could you send me URL of the page?

Yes,

www.ceafrso.fr/ceafrso15

You have quite strange site setup. All the links to images start with "/ceafrso15/../". What is reason to do it? Do you have special redirects/rewrites in .htaccess? Do you set live_site parameter in configuration.php?

it's Normal,
The default site www.ceafrso.fr is a 1.0.x joomla version.
The directory ceafrso15 contain a 1.5.x joomla version (site migration).
So pictures are /ceafrso15/....

live_parameter is set in the configuration file of the joomla 1.0.x version site, not in the 1.5.x version.

The error message dont appear if I select "don't rescale" in the adaptation method parameter.


What's the utility of the /images/..../Resized directory ?
