Prestashop server 500 error message

[TheStingPilot]

Hello,

I have running PrestaShop on an internal VMWARE Ubuntu 16.04 server. I have installed PS 1.7.3.0. After doing a test payment I received a 'white screen of death'. After enabling debugging in  defines.inc.php I get the errors as mentioned in the attachment. Disabling the latest added addons did not help.

Serverdetails:

You are using a custom module named Sementify.  Perhaps you should remove this module or contact the author for support?

I can confirm that after disabling this module the confirmation page is displayed correctly.

This may be caused by I have not set up Sementify correctly.
