hi. i upgraded one of my rc installations to 0.6 the other day. all worked fine until the next day when accessing the site returned :
Fatal error: Class 'rcmail' not found in /var/www/vhosts/subdomains/webmail-test/httpdocs/index.php on line 34
i re-uploaded the 0.6 files from the tar ball and this appeared to fix the problem, everything was working fine all day yesterday. i've just gone to access the site today and it's returned the same error. i can't find anything in the app logs or server logs. does anyone know why this would work for a bit and then just keep failing ? cheers.
