Can I install on server with php 4?

See above....

Thanks

For the latest version for vShare 2.6 needs PHP 5.x

Please see vshare requirements at

http://vshare.in/requirements.html

I run in cirtex host on php 4 and work fine, without the support for advanced this like save video from youtube directly and so on :)

if its working fine, then no probs.

when using vshare with php 4.x, remote upload or video import functions may not work properly.
