Hi,
I had the same problem ad I solved changing a row in the monoslideshow.php file.
Exactly, at row n. 413 I changed this:
$swf->add_flashvars( ‘dataFile’, urlencode (get_option (‘siteurl’) . ‘/’ . ‘index.php?callback=monoslideshow&gid=’ . $galleryID . $preset ) );
with:
$swf->add_flashvars( ‘dataFile’, urlencode (get_option (‘home’) . ‘/’ . ‘index.php?callback=monoslideshow&gid=’ . $galleryID . $preset ) );
In my case the home path is different than the site url path. In this way It finds the index.php file following the home path.
I’m not expertise on code issues but I solved that problem.
