Call to undefined function: imagettftext()
Error: This can manifest as a couple of errors:
Call to undefined function: imagettftext() ...
or
Warning: imagettftext(): Could not find/open font in ...
Solution: Those errors indicate that your PHP installation does not have True Type Font support compiled. If you have access—or your Host/server admin is willing—you can simply alter your PHP installation to have the True Type Font support compiled in.
Otherwise, you can go to Admin > Captcha Preferences and change the “Use TrueType Font for Captcha?” option to NO.
