hello

I installed (no problem) the mod on my site but when I go on the page, I have this message:

<urlset> </ urlset>

there is nothing on the page, why ?

thank you

This is Nuevoplayer forum, not for mods.
Both sitemap generators are fine for default clipshare or AVS scripts.
If there is something wrong with generator, means that there's something wrong with the script or it was custom changed.
Sometimes people also do not care about videos status. Video must be "public", should have "active" status to be taken into sitemap. Also it must be video located on own server, not embed code (Google accepts only own on-server videos). Those are most common issues and suggestions.
Other issues can be only caused by non standard script settings and we cannot help more without having access to files, also even if we have it - it cannot be a matter of free service.
