After moving a WordPress site from one server to a brand new server I ran into an issue with one of the WordPress plugins called MM-Forms. The MM-Forms WordPress plugin allows you to easily create contact forms that will either email filled out forms to you, store those forms in the MySQL database, or both email you and store the results in the database. The issue was the fact that the contact form was not displaying on the page it was configured to display on. After digging around a bit I located the issue by looking in the Apache logs. The issue ended up being with the PHP function called imagetypes. Below I describe the actual error noticed in the Apache logs, the CentOS RPM package that will provide the PHP function that was missing, and the yum logs from installing the package.
I was recently installing KBPublisher on a web server running Litespeed web server with both PHP and Ruby running on it. The initial check for KB Publisher complained about GD FreeType Support, GD FreeType Linkage, and GD JPG Support not being compiled into PHP. Its fairly easy to resolve this but may not be obvious to all so use the tips and directions below.
