I just tried to add some php to a site, and there is an error message that reads “GD Support not detected! GD required for this script.”
A quick search on Google led to this solution:
$ sudo apt-get install php5-gd
http://www.cyberciti.biz/faq/ubuntu-linux-install-or-add-php-gd-support-to-apache/
But one of the messages that came up on install suggests a conflict, i.e.:
dpkg: libgd2-noxpm: dependency problems, but removing anyway as you request:
webalizer depends on libgd2-noxpm (>= 2.0.33) | libgd2-xpm (>= 2.0.33); however:
Package libgd2-noxpm is to be removed.
Package libgd2-xpm is not installed.
I guess that I can live without Webalizer anyway. But always a worry when these things happen!
UPDATE – that problem has been quickly superceded by the message on the webpage:
Warning: session_start() [function.session-start]: Cannot send session cookie – headers already sent by (output started at /var/www/contact.html:6) in /var/www/formmailer.php on line 1
Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent (output started at /var/www/contact.html:6) in /var/www/formmailer.php on line 1
If you know how to fix this, please let me know!
