Thank you both very much! It worked and fixed the problem! You saved me from hours of work!
For future reference the problem was that ISPConfig was not writing at the hard disk.
I commented out the server.sh cron job:
#* * * * * /usr/local/ispconfig/server/server.sh > /dev/null >> /var/log/ispconfig/cron.log
then i run
rm -f /usr/local/ispconfig/server/temp/.ispconfig_lock
/usr/bin/php -q /usr/local/ispconfig/server/server.php
I had to install posix with:
yum install php-process
Rerun previous 2 commands. The missing updates updated and problem solved!!
Do you have any clue what could cause the problem? What is causing ISPconfig to stop writing?
