Running cron manually from the browser

Quickie question...

If the cron.php is run manually from the browser, are any results messages supposed to display on the browser screen?  All I get is a white screen, but my videos do get processed.

No, cron jobs do not show any output. If a error occures, it might when viewed in a browser, but those should go to the admin email address cron is setup to use.

Cron files are written specifically not to display output because humans don't read it.

OKay, just needed to know so I can toss that back to my host.  They are standing firm that the cron job command they give me is correct, and they are blaming the script as the reason why the cron won't run since they see no output when run manually.

It wasn't working manually, but then I found another thread here that had suggested php.ini settings.  I compared them to mine and made the suggested changes, and ran the cron manually.  My emails were suddenly sent and videos processed.

I'm a step closer to getting it all working, but I think i'm still gonna switch hosts.
