Wordpress upload 500 internal server error

[robbo007]

Hmm I seem to be getting an error now from the cron.d process:

Cron <root@sosaria> [ -x /usr/lib/php5/maxlifetime ] && [ -d /var/lib/php5 ] && find /var/lib/php5/ -type f -cmin +$(/usr/lib/php5/maxlifetime) -delete (failed)

find: invalid argument `-delete' to `-cmin'

It seems to be from my crontab:

sosaria:/etc/cron.d# cat php5
# /etc/cron.d/php5: crontab fragment for php5
# This purges session files older than X, where X is defined in seconds
# as the largest value of session.gc_maxlifetime from all your php.ini
# files, or 24 minutes if not defined. See /usr/lib/php5/maxlifetime

# Look for and purge old sessions every 30 minutes
09,39 * * * * root [ -x /usr/lib/php5/maxlifetime ] && [ -d /var/lib/php5 ] && find /var/lib/php5/ -type f -cmin +$(/usr/lib/php5/maxlifetime) -delete
sosaria:/etc/cron.d#


Any ideas?
