My forum was running OK first thing this morning but shortly after I logged in to the Control Panel the forum died (without me changing any settings). The error message in the log files are as follows:
[Wed Nov 16 08:47:07 2016] [error] [client 62.24.181.135] PHP Fatal error: Call to undefined function imagecreatetruecolor() in /var/zpanel/hostdata/zadmin/public_html/forum_pearldentalclinic_co_uk/core/vb/image/gd.php on line 498, referer: http://forum.pearldentalclinic.co.uk/core/image.php

There are several more of the same "undefined index" errors that I haven't bothered to list.
Can you suggest a cause & solution?
Thanks, Adam
