well... i have tried with a new basic instalation with no new modules. i install the jfslide and ther is the same problem. you can check at
www.kaquna.byethost24.com/joom/
you can see that is a slider at the background. the module is definited for all pages. if you click on, for example, "mapa del sitio" (left sidebar) the images don't appear, only the loader.
if i change the friendly url the module works at all pages...
where can the problem be?
many thanks
