Unable to add php code to Sites > Subdomain (Vhost) > Custom php.ini settings, ISPConfig 3.1 does not SAVE the information I can only CANCEL and changes are not saved.
No. What's strange if I add shortopen_tag=On (without underscore after short) i can save it short_open_tag=On (correct syntax) i cannot save it
Updating existing ISPConfig 3 installation seemed to fixed above issue: cd /tmp wget http://www.ispconfig.org/downloads/ISPConfig-3.1.1p1.tar.gz tar xvfz ISPConfig-3.1.1p1.tar.gz cd ispconfig3_install/install php -q update.php
have you been playing with modsecurity lately? that could explain it - eg. modsecurity was blocking your request because of the short_open_tag, then you reinstall, which disabled modsecurity in the ispconfig vhost, so it works again. If that's the case, there's a post at https://www.howtoforge.com/community/threads/mini-howto-modsecurity-crs-3-0-on-debian-jessie.74898/ where you can take up the issue, where you can (rather, should? post the modsec rule or log entry that you're hitting to be added as an exception. hopefully the work there will make it into the official modsecurity crs3 ruleset in the future.
