Hi, One of our client's ISP Config control panel no longer works. When I put the URL in my browser, It doesn't give me the login prompt. Just the ISP Config header. See image below: I've enabled debugging via the backend but the ispconfig log is just full of: 22.11.2017-10:30 - DEBUG - Remove Lock: /usr/local/ispconfig/server/temp/.ispconfig_cron_lock 22.11.2017-10:31 - DEBUG - Remove Lock: /usr/local/ispconfig/server/temp/.ispconfig_cron_lock 22.11.2017-10:32 - DEBUG - Remove Lock: /usr/local/ispconfig/server/temp/.ispconfig_cron_lock 22.11.2017-10:33 - DEBUG - Remove Lock: /usr/local/ispconfig/server/temp/.ispconfig_cron_lock 22.11.2017-10:34 - DEBUG - Remove Lock: /usr/local/ispconfig/server/temp/.ispconfig_cron_lock 22.11.2017-10:35 - DEBUG - Remove Lock: /usr/local/ispconfig/server/temp/.ispconfig_cron_lock 22.11.2017-10:36 - DEBUG - Remove Lock: /usr/local/ispconfig/server/temp/.ispconfig_cron_lock 22.11.2017-10:37 - DEBUG - Remove Lock: /usr/local/ispconfig/server/temp/.ispconfig_cron_lock 22.11.2017-10:38 - DEBUG - Remove Lock: /usr/local/ispconfig/server/temp/.ispconfig_cron_lock I've tried removing the lock file and running server.sh again, but I then get: Set Lock: /usr/local/ispconfig/server/temp/.ispconfig_lock finished. I've upgraded ISP Config to ISPConfig 3.1.8p1 and it has made no difference. Any ideas what has gone wrong here? Server spec/OS details are below. This is an older server which we plan to upgrade some time in the next few months, but it would be great if there was a way to fix this in the meantime. Ubuntu 12.04 Apache 2.2.22 PHP 5.3.10 Thanks!
