try running the cron as apache(if on centos) or www-data(if on ubuntu) for blesta as that resolved it for myself though aren't you related to the person who took over ftpit lol ?
since people want copy & paste to fix this run this in root ssh on the vm/machine with blesta on it
centos:
crontab -u apache -e
press insert
paste line given to you by blesta for the cron
press esc
type :wq
remember to remove the cron line from root cron if you put it in there like this:
crontab -e
press insert
delete all lines to leave it blank.
press esc
type :wq
fixed
ubuntu:
crontab -u www-data -e
press insert
paste line given to you by blesta for the cron
press esc
type :wq
remember to remove the cron line from root cron if you put it in there like this:
crontab -e
press insert
delete all lines to leave it blank.
press esc
type :wq
