session_start(); dies after publishing to nginx server

session_start(); dies after publishing to nginx server

pI put this all together on a server running apache and everything worked
fine, I tested multiple times./p pI published it to a server running nginx
and now I can't even load the first page because codesession_start()/code;
is dying./p pI've done a lot of research and I'm pretty sure it's not the
nginx server because I've seen other codephpinfo()/codes and mine is the
same as other working ones. phpinfo: session Session Support enabled
