For CentOS users

yum install php-gd

It is normally an installation problem...

I had the same kind of error and I fixed it like the following... On the initial WEB ZABBIX setup.. after accepting license and providing DB user/pwd... the setup PHP program updates the configuration file and 'tries' to save it in /usr/share/zabbix/conf... if for any reason it doesn't work, the installation seams to be set with bad information.

After resinstalling the php-gd and zabbix-web packages, I insured to delete the /usr/share/zabbix/conf/zabbix-conf-php file and re-execute the WEB installation (Locally on the zabbix server machine as it need to save the conf file!). the file was properly saved and graph display worked after. One of these steps fixed the problem, quite sure it is the conf file as I initially had problems with the original setup.
