If your wiki works with the webbrowser and not from the command line, then the command line uses another php.ini (this is definitely so), or you're using another (old) version of php from your command line.

Check your php.ini for your command line (usually /etc/php5/cli/php.ini on Ubunutu) and check, if apc is enabled there, too. But for this your hosting provider should really support you, "i don't know" doesn't sound like a good answer ;)
