Suddely, I can't create new sites
I have ISPConfig 3.0.4 under Fedora15, with MySQL 5.5. I've had it up for months, and have created about 7 web sites under 3 clients, running things like Joomla, WordPress, basic web sites, and so on. Everything has been working perfectly.
However, today ISPConfig suddenly refuses to create new web sites. It all seems to work, as the new site appears in ISP's lists, so the database entry is being made. But -- the directories under /var/www/clients/client... are not created, and no vhost file appears in /etc/httpd/conf/sites-available/.
The only thing I've screwed with lately was a minor change to the session.save_path variable in php.ini, in order to get phpMyAdmin running -- it has been turned off since I don't like the security implications. However, setting it back hasn't fixed things. (On a side note, I would like a definitive opinion on how session.save_path should be set, either globally in php.ini, or in each of the vhost files)
I have pored over everything I can think of, but I haven't seen any error messages in logs, or other odd behaviour. All existing sites are still working fine, but I can't create any new ones, and this bugs me.
