I am having problems with the Vhosts file not updating when I make changes So I checked the log and it says: WARN - /root/ispconfig/scripts/lib/config.lib.php, Line 2667: WARNING: could not . /etc/apache2/envvars && httpd -t &> /dev/null followed one second later by WARN - /root/ispconfig/scripts/lib/config.lib.php, Line 2681: httpd syntax seems to contain errors, reloading with old configuration but if I do . /etc/apache2/envvars && httpd -t on the shell, I get Syntax OK So how can I look for the problem? [Later:] Found it! I downloaded the Vhosts.conf and the new one that it rejected. When I did a diff on the two files, I found that there was some rubbish in one of the lines. It looks as if it had been accidentally typed into the "Apache Directives (Optional): " box in ISP Manager, but instead of creating an error message, it simply refused to use the new conf file. I cleared the Directives box, saved and all is well again!
