You will have to disable Catpcha.

Open your SystemGlobals.properties / jforum-custom.conf and set to "false" the keys "captcha.posts" and "captcha.registration"

Kulbir, so far it's not clear why those errors occur with the captcha library. It simply does not make any sense.

If someone has something that may help, please share with us!

This happens because you don't have X available.
You need to run Xvfb, then the captcha will work. This is how I do it.

Cheers.
